Takotsubo Cardiomyopathy and New-Onset Right Bundle Branch Block in Uncomplicated Right Ventricle Pacing

Abstract

Normally in the right ventricular (RV) paced rhythm, the electrocardiogram pattern will be of left bundle branch block (LBBB) pattern. A small percentage of patients can have right bundle branch block (RBBB) pattern in uncomplicated RV pacing. We are reporting here a rare occurrence of a new-onset RBBB in an RV paced patient which was coinciding with the onset of takotsubo cardiomyopathy following pulse generator re-implantation procedure.
