Özet
Left bundle branch area pacing (LBBAP) is an effective strategy for restoring electro mechanical synchrony; however, its potential to suppress a high burden of concomitant atrial and ventricular ectopy remains to be fully elucidated. We present a 57-year-old male patient with left bundle branch block (LBBB)-induced cardiomyopathy who experienced significant improvement in left ventricular ejection fraction (LVEF) and marked suppression of both premature ventricular contractions (PVCs) and supraventricular extrasystoles (SVEs) after LBBAP. At 6 months of follow-up, LVEF increased to 58%, PVCs decreased to 200 per day, and SVEs disappeared. LBBAP can reverse mechanical dyssynchrony and suppress a high burden of ectopy.
