Greater terminal S-wave amplitude in lead V2 is associated with increased acute endocardial ablation success in left ventricular outflow tract arrhythmias, with ~75% of cases successfully ablated.
Does greater terminal S-wave amplitude in lead V2 predict acute successful endocardial ablation in patients with left ventricular outflow tract idiopathic ventricular arrhythmias?
Greater terminal S-wave amplitude in lead V2 with monophasic R waves in other precordial leads is a novel ECG marker that predicts acute successful endocardial ablation in a subtype of LVOT idiopathic ventricular arrhythmias.
Absolute Event Rate: 0% vs 0%
Among patients with this ECG phenotype, approximately 75% can be successfully ablated endocardially at the LCC/RCC commissure subvalvularly or the anterior mitral annulus near the AMC. Greater terminal S-wave amplitude in lead V2 is associated with an increased likelihood of acute endocardial ablation success.
