Background: Brugada syndrome is a potential cause of sudden cardiac death (SCD) and is characterized by a distinct ECG, but not all patients with A Brugada ECG develop SCD. In this study we sought to examine if an artificial intelligence (AI) model can predict a previous or future ventricular fibrillation (VF) episode from a Brugada ECG.Methods and Results: We developed an AI-enabled algorithm using a convolutional neural network. From 157 patients with sus-pected Brugada syndrome, 2,053 ECGs were obtained, and the dataset was divided into 5 datasets for cross-validation. In the ECG-based evaluation, the precision, recall, and F1 score were 0.79 & PLUSMN;0.09, 0.73 & PLUSMN;0.09, and 0.75 & PLUSMN;0.09, respectively. The average area under the receiver-operating characteristic curve (AUROC) was 0.81 & PLUSMN; 0.09. On per-patient evaluation, the AUROC was 0.80 & PLUSMN;0.07. This model predicted the presence of VF with a precision of 0.93 & PLUSMN;0.02, recall of 0.77 & PLUSMN;0.14, and F1 score of 0.81 & PLUSMN;0.11. The negative predictive value was 0.94 & PLUSMN;0.11 while its positive predictive value was 0.44 & PLUSMN;0.29. Conclusions: This proof-of-concept study showed that an AI-enabled algorithm can predict the presence of VF with a substantial performance. It implies that the AI model may detect a subtle ECG change that is undetectable by humans.
