idiopathic ventricular arrhythmia,IVA
Conditions
Interventions
Experimental Group:Preoperative AI-based prediction and guidance for localizing the origin of idiopathic ventricular arrhythmias in the outflow tract to guide surgery.
Control group:No AI-based preoperative prediction or guidance was used
conventional surgical methods were applied instead.
