ICD in Pediatric Patients With Brugada Syndrome: Event-Free Survival Based on Kaplan-Meier Method
The event-free survival was estimated by the Kaplan-Meier method and compared by the log-rank test. This figure shows graphics analyzing freedom from appropriate shocks according to previous sudden cardiac death (SCD) (left) and spontaneous type I electrocardiographic (ECG) pattern (right). The time is measured in years since device implantation. Note that the incidence of appropriate therapy at 5 years post ICD implantation is 50% in patients that initially presented with SCD, and 70% in those patients that presented with a spontaneous type I ECG pattern.
