Paroxysmal supraventricular tachycardia with persistent ventriculoatrial block

We report the case of a 64-year-old patient with paroxysmal supraventricular tachycardia and persistent VA block. Induction and maintenance of tachycardia occurred without apparent activation of the atria. Diagnostic characteristics were most compatible with AV nodal reentrant tachycardia (AVNRT). Automatic junctional tachycardia and orthodromic nodoventricular or nodofascicular reentry tachycardia were considered in the differential diagnosis. Upper common pathway block during AVNRT may be explained by either intra-atrial conduction block or purely intranodal confined AVNRT. The arrhythmia was cured by a typical posteroseptal ablation approach guided by slow pathway potentials.     

舌下含服维拉帕米治疗阵发性室上性心动过速临床研究

Clinical experience with surgery for paroxysmal supraventricular tachycardia: a report of 103 cases

One-hundred-and-three patients underwent surgery for paroxysmal supraventricular tachycardia (PSVT). In eighty-three patients (81%), PSVT was due to an accessory atrioventricular pathway (Group I) and in 20 (19%) to Atrioventricular Junctional (AV nodal) Reentrant Tachycardia (AVJRT:Group II). Initial surgery successfully divided 77 of 83 accessory pathways, including 58 of 60 left free wall pathways, 12 of 15 posteroseptal pathways, six of seven right free wall pathways and one anteroseptal pathway. Twenty patients had successful surgery for AVJRT. Surgery was performed with low morbidity and no early or late mortality in either group. One patient in each group required permanent pacemaker implantation. Immediate (within one week) postoperative electrophysiological study using epicardial wires was performed in 96% of patients and repeat electrophysiological study six months later was possible in 65/103 (63%) patients. Patients with surgery for accessory pathways were followed-up for a mean 34 ± 23 months, while those with surgery for AVJRT for a mean of 13 ± seven months. No patient with successful surgery has had a clinical recurrence of PSVT. Thus the results indicate that surery is a safe and curative therapy for patients with PSVT.

Evaluation of psychopathology in patients with paroxysmal supraventricular tachycardia

BACKGROUND: A higher prevalence of anxiety- and depression-related symptoms are expected in patients with at least one somatic disease and who are on medications compared with the general population. OBJECTIVES: To determine if patients with paroxysmal supraventricular tachycardia (PSVT) show a higher prevalence of anxiety and depressive symptoms compared with a control population. The induction of depressive symptoms by beta-blockers or calcium channel blockers was also evaluated. METHODS: Twenty-five patients (17 women, eight men) with documented PSVT (atrioventricular re-entrant tachycardia or atrioventricular nodal re-entrant tachycardia) were evaluated by a battery of questionnaires and inventories, which provide information about the presence of symptoms of anxiety and/or depression. All patients were examined by a psychiatrist and completed the following five scales: Symptom Checklist-90, Hamilton Anxiety Scale, Hamilton Depression Rating Scale, Zung's Self-Rating Depression Scale and Beck Self-Assessment Depression Scale. RESULTS AND CONCLUSIONS: The majority of the evaluations (Hamilton Anxiety Scale, Beck Self-Assessment Depression Scale, Zung's Self-Rating Depression Scale), did not show a higher incidence of severe symptoms of depression in the group of patients with PSVT. However, the Hamilton Depression Rating Scale rated the symptoms of depression as significant, but the score was low enough to be considered nonsignificant. According to the Symptom Checklist-90, men perceived the presence of the cardiological disease more intensively and more negatively than women (P=0.1). Psychiatric history and therapy with psychopharmacological agents were comparable in both groups. It was noted that patients had sporadic contacts with a psychiatrist or a psychologist, but this was not directly associated with PSVT.     

经食道心房调搏诊断阵发性室上性心动过速的临床价值

目的探讨经食管心房调搏（TEAP）检查诊断阵发性室上性心动过速（PSVT）的临床价值。方法纳入临床诊断为PSVT患者74例,通过TEAP检查予以诱发以及终止PSVT,记录并分析PSVT心电图参数,包括诱发窗口、诱发频率、房室结不应期等,并与心腔内电生理（IEPS）检查结果进行比较。结果 TEAP检查的诱发窗口、诱发频率、房室结不应期与IEPS检查结果相关性良好（P＜0.05）, TEAP检查诊断PSVT的符合率达83.8%（62/74）,诱发的PSVT均能通过TEAP予以终止。结论 TEAP检查可有效评估PSVT的电生理特性,准确率高,值得临床广泛应用。
