Figure 1: Left bundle branch pacing for NICM with LBBB. A – PVCs with changing morphology from QS to qR pattern (VES1) in lead V1 noted during rapid rotation. B – LBB paced QRS morphology mimicked VES1 with duration of 122ms and pLVAT of 65ms. C- Non selective (first 2 beats) to selective LBB capture (last 2 beats) at near threshold output. D- Final 12 lead electrocardiography (ECG) after RBB delay correction by optimizing the AV delay (QRS duration 98ms). His d – distal His bundle electrogram, LBB and LBU – Pacing lead electrogram bipolar and unipolar respectively
