When to go epicardially during ventricular tachycardia ablation Role of surface electrocardiogram

Abstract

Early recognition of ventricular tachycardias (VTs) with epicardial circuits is crucial. Surface electrocardiogram (ECG) suggesting an epicardial origin could guide ablation procedures and increase success rates. A 35-year-old female patient with VT treated by combined epicardial and endocardial ablation approach is presented in this report, and the role of surface electrocardiogram and timing of epicardial access is discussed. © 2013 Akadémiai Kiadó, Budapest.
