NCT06172842

Brief Summary

From 2020 to 2023, patients with primary electrical disease (idiopathic ventricular fibrillation, long QT syndrome, Andersen-Tawil syndrome type I, Brugada syndrome, early repolarization syndrome, CPVT, and short QT syndrome) were first diagnosed at Sun Yat-sen Memorial Hospital of Sun Yat-sen University, and clinical data and echocardiographic indicators were recorded. Follow-up is until December 30, 2025 or endpoint event occurs. Endpoint events were defined as sustained ventricular tachycardia, ventricular fibrillation, sudden cardiac death, ICD discharge events, all-cause death, heart failure and heart transplantation, which were statistically analyzed as a composite endpoint of cardiovascular analysis. The predictors of primary electrical disease and the risk factors for adverse cardiovascular events were analyzed.
