Tpeak-Tend interval as a new risk factor for arrhythmic event in patient with Brugada syndrome
摘要
Abstract
Objective:To evaluate Tpeak-Tend (Tp-e) interval in surface standard ECG as a new risk factor for arrhythmic event in patient with Brugada syndrome. Methods: 23 male patients with Brugada syndrome and 20 male patients with paroxysmal supraventricular tachycardia (PSVT) as the control group were investigated in this study. Tp-e interval in surface standard ECG was compared between BrS and PSVT patients. Results: Tp-e interval in BrS patients was significantly longer than that in PSVT patients (109.57±22.86 ms vs. 88.50±13.08ms, P＜0.05). There was significant difference in Tp-e interval between 16 BrS patients with arrhythmic events (including syncope, clinical ventricular fibrillation [VF] and programmed electrical stimulation [PES]-induced VF) and 7 BrS patients without arrhythmic events and PSVT patients (118.12±20.40ms vs.90.00±15.27ms, P＜0.05; 118.12±20.40ms vs. 88.50±13.08ms, P＜0.05). However, Tp-e interval was similar in BrS patients without arrhythmic events and PSVT patients (90.00±15.27ms vs 88.50±13.08ms, P＞0.05). Conclusion: The prolongation of Tp-e interval could serve as a new noninvasive event predictor for arrhythmic events in patients with Brugada syndrome.关键词
