Accurate interpretation of the intracardiac electrogram (EGM) is essential to the successful ablation of idiopathic focal ventricular arrhythmias (VA). Early sharp distal bipolar EGM (biEGM), which may signify the initial activation of focal VA, is often targeted, but in an empiric fashion rather than quantitative terms.
