Paced QRS morphology mimicking complete left bundle branch block induced by right ventricular pacing is associated with pacing?induced cardiomyopathy

Journal of Cardiovascular Electrophysiology

Complete left bundle branch block (CLBBB)-like QRS morphology of right ventricular pacing at pacemaker implantation satisfying the American Heart Association/American College of Cardiology Foundation/Heart Rhythm Society criteria of CLBBB was associated with development of pacing induced cardiomyopathy.

This ECG shows a sinus bradycardia with a normal conduction pattern (normal PR, normal QRS, and normal QTc), normal axis, normal R-wave progression, normal voltages. Hypothermia can also produce bradycardia and J waves, with a pseudo-STEMI pattern. Heart Rhythm 2010 Hudzik B, Gasior M. There is marked sinus bradycardia.
