【 摘 要 】
Background-We retrospectively investigated the value of clinical and ECG findings as well as QT-QRS dispersion in predicting the risk of sudden death in patients with arrhythmogenic right ventricular cardiomyopathy (ARVC). Methods and Results-Duration and interlead variability of the QT interval and QRS complex were measured manually from standard ECGs in 20 sudden death victims with ARVC diagnosed at autopsy (group I), in 20 living ARVC patients with sustained ventricular tachycardia (group II), in 20 living ARVC patients with less than or equal to3 consecutive premature ventricular beats (group III), and in 20 control subjects (group IV). QT and QRS dispersions were greater in group I (77.5 +/- 10.6 ms for QT and 45.7 +/-8.1 ms for QRS) compared with group II (64.5 +/- 13.9 ms for QT [P=0.001] and 33.5 +/-8.7 ms for QRS [P=0.0004]) and in group II compared with group III (48 +/-8.9 ms for QT [P<0.0001] and 28
