BACKGROUND: QT rate dependence is one of the major properties of ventricular repolarization, with its circadian and autonomic modulations. The alteration of cardiac autonomic tone occurring in obstructive sleep apnea syndrome (OSAS) patients could explain the altered rate-dependent adaptation of the myocardial repolarization. Thus, we postulated that dynamic alterations in QT interval adaptation could be ameliorated in OSAS patients under continuous positive airway pressure (CPAP) treatment. To assess ventricular repolarization features in patients with OSAS, we compared QT parameters and their dynamicities along RR intervals from 24-hour ECG. METHODS: The study groups consisted of 38 consecutive OSAS patients and 38 healthy age-matched subjects. The syndrome was confirmed for OSAS patients according to standard polysomnographic criteria (apnea plus hypopnea index: 56.9 +/- 28.4/h). A second polysomnography synchronized with 24-hour ECG Holter and realized under efficient CPAP therapy confirmed the control of sleep-related breathing disorder. RESULTS: QT length related to heart rate was found significantly altered in patients with OSAS compared with controls (QTend/RR slope: -0.126 +/- 0.031 vs -0.173 +/- 0.038; P < 0.01). This flattened relationship was significantly improved with the treatment of the OSAS (-0.151 +/- 0.051; P < 0.01 vs pretreatment status). There was no significant impact of CPAP therapy on ventricular ectopic activity as well as on static repolarization parameters (QT, RT, QTc, RTc) measured separately over daytime and nighttime. CONCLUSIONS: The prognostic implications of such findings and the protective role of CPAP treatment to prevent sudden cardiac death in OSAS need to be evaluated. 相似文献

Background: In the most prevalent LQT1 form of inherited long QT syndrome symptoms often occur during abrupt physical or emotional stress. Sympathetic stimulation aggravates repolarization abnormalities in experimental LQT1 models. We hypothesized that autonomic function tests might reveal the abnormal repolarization in asymptomatic LQT1 patients.
Methods: We measured heart rates (HRs) and QT intervals in nine asymptomatic carriers of a C-terminal KCNQ1 mutation and 8 unaffected healthy subjects using an approach of global QT values derived from 28 simultaneous electrocardiographic leads on beat-to-beat base during Valsalva maneuver, mental stress, sustained handgrip, and light supine exercise.
Results: LQT1 patients exhibited impaired shortening of both QTpeak and QTend intervals during autonomic interventions but exaggerated lengthening of the intervals—a QT overshoot—during the recovery phases. The number of tests with a QT overshoot was 2.4 ± 1.7 in LQT1 patients and 0.8 ± 0.7 in unaffected subjects (P = 0.02). Valsalva strain prolonged T wave peak to T wave end interval (TPE) in LQT1 but not in unaffected patients. LQT1 patients showed diminished HR acceleration in response to adrenergic challenge whereas HR responses to vagal stimuli were similar in both groups.
Conclusions: Standard cardiovascular autonomic provocations induce a QT interval overshoot during recovery in asymptomatic KCNQ1 mutation carriers. Valsalva maneuver causes an exaggerated fluctuation of QT and TPE intervals partly explaining the occurrence of cardiac events during abrupt bursts of autonomic activity in LQT1 patients. 相似文献

Background: LQT1 subtype of long QT syndrome is characterized by defective IKs, which is intrinsically stronger in the epicardium than in the midmyocardial region. Electrocardiographic QT peak and QT end intervals may reflect complete repolarization of epicardium and midmyocardial region of the ventricular wall, respectively. Repolarization abnormalities in LQT1 carriers may therefore be more easily detected in the QT peak intervals. Methods: Asymptomatic KCNQ1 mutation carriers (LQT1, n = 9) and unaffected healthy controls (n = 8) were studied during Valsalva manoeuvre, mental stress, handgrip and supine exercise. Global QT peak and QT end intervals derived from 25 simultaneous electrocardiographic leads were measured beat to beat with an automated method. Results: In unaffected subjects, the percentage shortening of QT peak was greater than that of QT end during mental stress and during the recovery phases of Valsalva and supine exercise. In LQT1 carriers, the percentage shortening of the intervals was similar. At the beginning of Valsalva strain under abrupt endogenous sympathetic activation, QT peak shortened in LQT1 but not in control patients yielding increased electrocardiographic transmural dispersion of repolarization in LQT1. Conclusions: In asymptomatic KCNQ1 mutation carriers, repolarization abnormalities are more evident in the QT peak than in the QT end interval during adrenergic adaptation, possibly related to transmural differences in the degree of IKs block. 相似文献

To investigate the direct respiration-mediated vagal modulation of the QT interval variability, spectral analyses of the RTp interval (from the R wave peak to the T wave peak) variability (RTpV) and the RR interval variability (RRV) were performed in 12 subjects with normal ventricular repolarization under three conditions while the respiration frequency was kept at 0.2 Hz: during sinus rhythm, during fixed atrial pacing, and during fixed atrial pacing with autonomic blockade. The cross-spectrum between the RRV and RTpV was quantified by the squared coherence. During sinus rhythm the RRV power spectrum showed two peaks: a broad peak in the low frequency (LF) band and a sharp peak at 0.2 Hz which corresponded to the controlled respiration frequency. The RTpV power spectrum showed corresponding peaks to the RRV peaks in both the LF and high frequency (HF) bands with high coherence (mean maximum values of the squared coherence in the LF band 0.59 ± 0.22, and in the HF band 0.74 ± 0.14). During atrial pacing mean total power of the RTpV decreased from during sinus rhythm (from 16.3 ± 5.6 ms2 to 12.9 ± 5.4 ms2 , P < 0.05) and the RTpV spectral peaks were abolished in both the LF and HF bands concordant with disappearance of the RRV peaks. Autonomic blockade gave no additional change to the RTpV power spectrum independently of the RRV during fixed atrial pacing. The present study suggested that the direct respiration-mediated vagal modulation may not affect the short-term variability of the QT interval in subjects without repolarization abnormality. 相似文献

QT rate dependence is one of the major properties of ventricular repolarization with its circadian and autonomic modulations. The authors postulated that dynamic alterations in QT interval adaptation could help characterize patients with cardiac autonomic alterations, like those with obstructive sleep apnea syndrome (OSAS). To assess ventricular repolarization features in patients with OSAS, QT parameters and their dynamicity along RR intervals were compared from 24-hour ECG data of patients with and without this syndrome, assessing cardiac autonomic nervous system equilibrium by means of time-domain and frequency-domain analyses of heart rate variability (HRV). The study group consisted of 74 consecutive patients referred to the Sleep Laboratory for clinically suspected OSAS. The syndrome was confirmed in 30 (40.5%) patients according to standard polysomnographic criteria. QT length related to heart rate (HR) was found significantly shorter for HR < 70 beats/min in patients with OSAS (−1.32 ± 0.35) compared with patients without OSAS (−1.99 ± 0.40; P < 0.01) . This flattened relationship was correlated with the severity of the sleep related disorder. Using multiple linear regression analysis, the apnea/hypopnea index and nocturnal normalized high frequencies (HFnu) were the most significant predictors of the QT/RR slope (R = 0.61; P < 0.0001) . OSAS is significantly associated with a flattened relationship between QT duration and RR interval at low HRs. The alteration of cardiac parasympathetic tone occuring in severe OSAS patients may explain this altered rate dependent adaptation of myocardial repolarization. (PACE 2003; 26[Pt. I]:1446–1453) 相似文献

The present study investigated the nature of negative cognitions in anorexia and bulimia nervosa. On the basis of a specially constructed self-statement inventory, 62 anorexics and bulimics rated their depressotypic and negative weight-related cognitions as more frequent, emotionally intense, uncontrollable, guilt-inducing, and plausible than a student nurse control group. For the anorexic and student samples, thoughts of loss and failure were uniquely predictive of dysphoria, while cognitions of body dissatisfaction and food preoccupation were specifically associated with eating disturbance.Appreciation is expressed to Professor G. F. M. Russell for permission to collect data from patients of the Maudsley Hospital Eating Disorder Unit. We would also like to thank the patients of this unit, as well as the students and faculty of the Saint John School of Nursing, for their participation in this study. 相似文献

Traditionally, anorexia nervosa (AN) was understood to exist exclusively among underweight individuals and weight was used to assess level of severity and course of treatment. Recent trends have found a growing number of individuals presenting with AN or atypical AN (AAN) (i.e., those who remain with weight in a “normal” or “healthy” range despite significant weight loss) have a premorbid history of overweight/obesity. Individuals with AN/AAN and premorbid overweight/obesity represent an especially metabolically vulnerable population as with either AN or AAN, there is marked weight loss. Patients with AAN present a specific challenge as healthcare professionals must identify a clinically significant eating disorder in adolescents of potentially “normal” weights and then must balance their knowledge and training of traditional treatment of AN with obesity treatment and prevention. Currently, there are no evidence-based treatments to guide medical and mental health professionals regarding weight restoration, medical stabilization, and psychological treatment in patients with AN/AAN with a history of overweight/obesity while also addressing risk prevention for obesity. 相似文献

Chronotropic incompetence (CI), characterized by an attenuated heart rate (HR) response to exercise could participate to the limitation of exercise capacity in anorexia nervosa (AN). Therefore, we evaluated the role of cardiac sympathetic responsiveness in AN patients. In addition, the ambulatory value of autonomic control using spectral analysis of heart rate variability (HRV) was determined and correlated to maximal exercise performance. Twenty-two patients hospitalized for weight loss and suspicion of AN were included in the study. All performed a symptom-limited exercise test with measurement of gas exchange for chronotropic response to exercise evaluation. Holter ECG recordings allowed daytime and night-time spectral domain HRV analysis in order to evaluate the alteration of sympathetic control of HR in free-living conditions. CI defined as a failure to achieve 80% of heart rate reserve (%HRR) was observed in 13 (59%) patients (CI+). This group presented a higher body mass deficit than the group without CI (CI-; -35.1 +/- 8.7% versus -26.1 +/- 10.7%; P<0.05). Obviously, patients with a lower body mass index (BMI < 16 kg m(-2), n = 14) revealed a more severe limitation to maximal exercise with a lower peak HR, a lower peak Vo(2), and a lower maximal O(2) pulse (P<0.05). BMI was significantly correlated to peak Vo(2), maximal HR, and %HRR achieved at peak exercise. Daytime HRV parameters reflecting the sympathetic autonomic equilibrium (LF nu, LF/HF ratio) were significantly lower in CI+ patients. Blunted sympathetic response to maximal exercise is frequent and correlated to weight deficit. The present data suggest a major autonomic derangement in AN characterized by a cardiac sympathetic withdrawal. 相似文献

QT Interval Dispersion and its Clinical Utility 总被引:16,自引:0,他引:16
QT dispersion as a measure ofin-terlead variations of QT interval duration in the surface 12-lead ECG is believed to reflect regional differences in repolarization heterogeneity and thus, may provide an indirect marker of arrhythmogenicity. Methodology for determining QT dispersion and reproducibility of this parameter vary significantly between studies and, together with some other unresolved problems witb QT dispersion assessment, often lead to contradictory suggestions about potential clinical utility of this parameter. The results of our own study in 213 survivors of myocardial infarction, together with a comprehensive review of the literature, suggest that most of these inconsistencies reflect incomplete understanding of electrocardiographic correlates of both normal and abnormal ventricular repolarization. The application of more objective techniques, such as spectral analysis or combined assessment of different parameters (e.g., area beneath the T wave and its symmetricity) may add a new dimension to the noninvasive assessment of ventricular repolarization. 相似文献

Impact of electrocardiogram recording format on QT interval measurement and QT dispersion assessment
Faber TS Kautzner J Zehender M Camm AJ Malik M 《Pacing and clinical electrophysiology : PACE》2001,24(12):1739-1747
The aim of this study was to determine the effect of recording conditions on the operator dependent measures of QT dispersion in patients with known and/or suspected repolarization abnormalities. Among several methods for risk stratification, QT dispersion has been suggested as a simple estimate of repolarization abnormalities. In a cohort of high and low risk patients, different components of the repolarization process were assessed in the 12-lead ECG using three different paper speeds and amplifier gains. To assess measurement error and reproducibility, a straight line was repeatedly measured. The operator error was 0.675 +/- 0.02 mm and the repeatability of the measurement error was 31 +/- 6%. The QT interval was most frequently measurable in V2-V5. Depending on the lead selected for analysis, the incidence of visible U waves was greatest in the precordial leads with high amplifier gain and low paper speed, strongly affecting QT interval measurement. The timing of the onset of the QRS complex (QRS onset dispersion) or offset of the T wave was strongly dependent on the paper speed. Paper speed, but not amplifier gain, had a significant shortening effect on the measurement of the maximum QT interval. As QT interval measurement in each ECG lead incorporates QRS onset and T wave offset (depending on the number of visible U waves), the dispersion of each of these parameters significantly affected QT dispersion. Thus, QT dispersion appears to reflect merely the presence of more complex repolarization patterns in patients at risk of arrhythmias. 相似文献

Summary. Changes in QT, QT peak (QTp) and terminal T-wave, Tp–Te (QT–QTp) were studied in 11 apparently healthy subjects during and after a standardized exercise test. ECG was recorded at scalar lead positions. Averaged complexes were later analysed by computer for the different time intervals. QT and QTp decreased in parallel with increasing heart rate with a ratio QTp/QT of 0·80 ± 0.02 at rest and 0·74 ± 0·02 at maximal heart rate around 170. After exercise QT and QTp prolonged disproportionately slower than heart rate, reaching the relation observed during exercise only 9·5 min post exercise. Tp–Te was 75 ± 10 ms at rest and 65 ± 8 ms at maximal heart rate. The decrease was significant (P<0·001). The main part of the rate-associated shortening of the QT interval occurred in the QTp interval where it was about six to seven times larger than in the Tp–Te interval. In conclusion, QT and QTp decreased similarly with heart rate during exercise. Post exercise there was an initial slower return of these intervals to the resting state than for heart rate. Tp–Te changes were minimal. 相似文献

Linear and non-linear heart rate variability measures in chronic and acute phase of anorexia nervosa
Platisa MM Nestorovic Z Damjanovic S Gal V 《Clinical physiology and functional imaging》2006,26(1):54-60
Previous results on heart rate variability (HRV) analysis in anorexia nervosa (AN) include some apparently conflicting data. In order to find out the reason for different results and to improve understanding of autonomic control in AN we compare HRV in acute and chronic AN. Spectral powers, fractal scaling exponent and sample entropy were computed from 24 h RR series derived from Holter ECG recordings in 17 anorexic patients, nine chronic and eight healthy women. We found that all linear and non-linear HRV measures change in different direction in acute and chronic AN. Acute AN is characterized by decreased HR and increased HRV. In chronic AN, HR is increased, HRV reduced and the difference between awake and sleeping values is high. HRV measures are associated with body mass index only in chronic AN. As HRV measures are significantly different between acute and chronic AN, we propose that HRV analysis might provide additional data in clinical practice. 相似文献

HARDIN PK. Nursing Inquiry 2003; 10 : 209–217 Shape‐shifting discourses of anorexia nervosa: reconstituting psychopathology This article explores how the circuitous relationship between individuals, the media, and discursive systems replicate and reinforce the act of self‐starvation in young women. Using a feminist poststructuralist methodology, the focus of this article is on how discourses and institutional practices operate to position young women who take up the subject position of wanting to be diagnosed as anorexic. Utilizing data from online accounts and individual interviews, I attend to the ways in which young women are institutionally positioned as ‘anorexics’ and the effects that those positions have on their behaviors, in addition to reinforcing institutional practices that construct anorexia nervosa. Questions addressed through this inquiry are: How do institutional practices create and continue to constitute ‘anorexia nervosa’? How do discourses operate to position young women such that they are either included and/or excluded into the category of ‘anorexia nervosa’? What are the effects and consequences that emanate from these positionings? 相似文献

Abnormal repolarizaiion is associated with arrhythmogenesis. Because of controversies in existing methodology, new computerized methods may provide more reliable tools for the noninvasive assessment of myocardial repolarization from the surface electrocardiogram (ECC). Measurement of the interval between the peak and the end of the T wave (TpTe interval) has been suggested for the detection of repolarization abnormalities, but its clinical value has not been fully studied. The intrasubject reproducibility and reliability of automatic measurements of QT, QT peak, and TpTe interval and dispersion were assessed in 70 normal subjects, 49 patients with acute myocardial infarction (5th day; MI), and 37 patients with hypertrophic cardiomyopathy (HC). Measurements were performed automatically in a set of 10 ECCs obtained from each subject using a commercial software package (Marquette Medical Systems, Milwaukee, WI, U.S.A.). Compared to normal subjects, all intervals were significantly longer in HC patients (P < 0.001 for QT and QTp; p < 0.05 for TpTe); in MI patients, this difference was only significant for the maximum QT and QTp intervals (P < 0.05). In both patient groups, the QT and QTp dispersion was significantly greater compared to normal subjects (P < 0.05) but no consistent difference was observed in the TpTe dispersion among all three groups. In all subjects, the reproducibility of automatic measurement of QT and QTp intervals was high (coefficient of variation, CV, 1%-2%) and slightly lower for that of TpTe interval (2%–5%; p < 0.05). The reproducibility of QT, QTp, and TpTe dispersion was lower (12%–24%, 18%–28%, 16%–23% in normal subjects, MI and HC patients, respectively). The reliability of automatic measurement of QT, QTp, and TpTe intervals is high but the reproducibility of the repeated measurements of QT, QTp and TpTe dispersion is comparatively low. 相似文献

We analyzed Holter ECG recordings in 15 patients with episodes of prolonged RR intervals > 2.5 seconds. In 13 patients, the QT interval showed a linear prolongation when RR interval was < 1.5 seconds and became relatively flat at longer RR intervals. In the remaining two patients, the QT and RR intervals were correlated within physiological range of RR intervals. However, at longer RR intervals, the QT interval was unexpectedly shortened and constant. The paradoxically shortened QT interval observed in the present 2 cases may indicate an abnormal adaptation of repolarization time to an abrupt increase in the preceding RR intervals. 相似文献

Alteration of the QT/RR Relationship in Patients with Idiopathic Ventricular Tachycardia 总被引:1,自引:0,他引:1

It has been shown that alterations in QT/RR relationship may be associated with arrhythmogenesis in several clinical settings. In the present study the QT/RR relationship was studied in 20 patients with idiopathic ventricular tachycardia (12 men and 8 women, aged 41±14 years) compared to 20 normal subjects (9 men and 11 women, aged 39 ± 13 years). All the patients were off any antiarrhythmic drugs and had no evidence of intraventricular conduction defects. The QT intervals and their preceding RR intervals were measured on electrocardiogram strips from 24-hour Holter tapes at hourly intervals. The differences in the maximum, minimum, and mean of either the QT interval or its corrected values between patients with idiopathic ventricular tachycardia and normal subjects were not statistically significant. There was a significant correlation between the QT and RR intervals in normal subjects (γ= 0.73 ± 0.12, P < 0.05) and in patients with idiopathic ventricular tachycardia (γ= 0.80 ± 0.10, P < 0.05). However, the linear regression line of the QT interval against the RR interval were significantly (P < 0.001) altered in patients with idiopathic ventricular tachycardia (QT = 0.24 + 0.18 RR) compared to normal subjects (QT = 0.27 ± 0.12 RR). We conclude that although there is no significant change in the QT interval and its corrected values, the QT/RR relationship is significantly altered in patients with idiopathic ventricular tachycardia as compared to normal subjects. This may be of importance in the pathogenesis of idiopathic ventricular tachycardia in these patients. 相似文献

ABSTRACT: Anorexia nervosa (AN) mainly affects girls or women between 13 and 45 years of age. According to previous studies, one of the reasons for the desire to be thin is low self‐esteem. The purpose of the study was to examine the self‐esteem of 38 female patients with AN between 16 and 25 years of age, before and after 3 months of treatment at a specialist ward for eating disorders in Göteborg, Sweden. A quantitative pre‐ and post‐assessment based on two self‐rating questionnaires, the Rosenberg Self‐Esteem Scale (RSE‐S) and three subscales (weight phobia, body dissatisfaction, and ineffectiveness) of Eating Disorder Inventory‐2 (EDI‐2), together with body mass index (BMI), were used in the study, which was conducted between June 2005 and March 2008. The results reveal that self‐esteem, BMI, weight phobia, and body dissatisfaction improved significantly between pre‐ and post‐treatment. The RSE‐S and EDI‐2 ineffectiveness correlate highly with one another, which lends support to convergent validity, and the internal consistency was high for both the RSE‐S and EDI‐2 ineffectiveness. The results indicate that the treatment was effective, as both patients' self‐esteem and BMI increased after completed treatment, which was the primary goal of the treatment at this ward. Future studies should focus on follow up and the way self‐esteem manifests itself at different points in time within an individual. 相似文献
