From: Idiopathic left ventricular outflow tract ectopy: a single focus with extremely divergent breakouts
The left and right panels show the 12-lead ECG of the PVC-1 and PVC-2 before and after initial ablation at the LCC, respectively. The middle panel shows disappearance of PVC-1 within few seconds after the beginning of ablation with subsequent appearance of PVC-2 eleven seconds later (blue arrow). Note the change in R wave amplitude in inferior leads and the shift of transition zone from V2/3 to V4.
