ABSTRACT
Objective To explore the value of T wave alternans (TWA) in prediction ventricular arrhythmias in post-op TOF children. Methods The characteristics of TWA were retrospectively analyzed in 36 post-op TOF patients and 120 age-matched normal children. The relationship of sustained TWA and ventricular arrhythmias was also analysed. Results Compared with normal children, the incidence of sustained TWA was significantly increased in post-op TOF group (χ2=6.98, P<0.05). In post-op TOF patients, the incidence of ventricular arrhythmia was much higher when sustained TWA was present (χ2=10.41, P<0.05). Conclusions There exists electrophysiological basis for ventricular arrhythmia in post-op TOF children. Sustained TWA has important value in prediction of ventricular arrhythmia of post-op TOF.
