Background
Despite a growing clinical interest in determining the heart rate recovery (HRR) response to exercise, the limits of a normal HRR have not yet been well established.Purpose
This study was designed to examine HRR following a controlled maximal exercise test in healthy, physically active adult men.Methods
The subjects recruited (n = 789) performed a maximal stress test on a treadmill. HRR indices were calculated by subtracting the first and third minute heart rates (HRs) during recovery from the maximal HR obtained during stress testing and designated these as HRR-1 and HRR-3, respectively. The relative change in HRR was determined as the decrease in HR produced at the time points 1 and 3 min after exercise as a percentage of the peak HR (%HRR-1/HRpeak and %HRR-3/HRpeak, respectively). Percentile values of HRR-1 and HRR-3 were generated for the study population.Results
Mean HHR-1 and HHR-3 were 15.24 ± 8.36 and 64.58 ± 12.17 bpm, respectively, and %HRR-1/HRpeak and %HRR-3/HRpeak were 8.60 ± 4.70 and 36.35 ± 6.79 %, respectively. Significant correlation was detected between Peak VO2 and HRR-3 (r = 0.36; p < 0.001) or %HRR-3/HRpeak (r = 0.23; p < 0.001).Conclusions
Our study provides normality data for HRR following a maximal Ergometry test obtained in a large population of physically active men. 相似文献5.

BACKGROUND: Cardiac catheterization has revolutionized the management of pediatric cardiac disease. There has been little information on adverse events during these cases from an anesthesia viewpoint. The aim of this audit was to determine the incident rate during pediatric cardiac catheterization as contemporaneously reported by the anesthetist and to identify both the types of events and which procedures had the highest risk. METHODS: Since 1993, data have been collected prospectively on an audit form for every anesthetic given in our institution, and in-theatre events were recorded on this form. We have reviewed the data collected on pediatric cardiac catheterizations over a period of 9 years. RESULTS: A total of 4454 cardiac catheterizations were recorded. The overall incidence of events was 9.3%. Cardiac catheterization with occlusion of a patent ductus arteriosus (PDA) or a secundum atrial septal defect (ASD) had the lowest event rate at 4.2%. The figure for cardiac catheterization with other therapeutic interventions was 11.6 and 9.3% for solely diagnostic cardiac catheterization. The event rate in infants under the age of 1 year was 13.9% compared with 6.7% for those children over the age of 1 year. Of the 253 reports from cardiac catheterizations that could be analyzed further, there were 91 major complications including four deaths, 72 minor complications and 90 other incidents. CONCLUSIONS: Adverse events occur more commonly during cardiac catheterization than during pediatric anesthesia in general. Cases with highest risk are those in the under 1 year olds and those including a therapeutic intervention other than PDA or ASD occlusion. 相似文献

The purpose of this study was to analyze the effects of 2 days/week versus 4 days/week of Whole Body Vibration (WBV) during eight weeks of WBV training on health-related quality of life (SF-36), balance and lower body strength, as well as short-term detraining (3 weeks) on balance and lower body strength among older adults. Thirty-four older adults were randomly assigned to a control group (Control; n = 11) or to one of the vibration training groups: WBV 2 days/week (WBV_2d; n = 11) or WBV 4 days/week (WBV_4d; n = 12). The WBV groups exercised for 8 weeks, following 3 weeks of detraining. Lower body strength increased significantly (p < 0.05) for both groups, WBV_2d and WBV_4d, after 8-week training. A significant reduction in strength was observed following 3 weeks of detraining only in WBV_2d group (p < 0.05). All variables of the SF-36 and the balance test did not change after intervention in any group. 2 days/week and 4 days/week of WBV during 8 weeks showed the same improvements on muscle strength. 3 weeks of detraining did not reverse the gains in strength made during 32 sessions of WBV.
Key points
- 2 days and 4 days per week of WBV training during 8 weeks showed the same improvements on muscle strength.
- 3 weeks of detraining did not reverse the gains in strength made during 32 sessions of WBV exercise.
- 3 weeks of detraining did reverse the gains in strength made during 16 sessions of WBV exercise.
