Postoperative rate induced left bundle branch block after craniotomy
Abstract
Rate induced left bundle branch block (LBBB) is a rare peri-operative phenomenon. We encountered rate related LBBB in a 72 year old patient who had undergone a craniotomy.
Acute coronary event was ruled out by doing serial troponin-I levels and absence of new onset regional wall motion abnormalities on echocardiogram. The electrocardiographic changes reverted to normal after controlling the rate with β blockers. Further cardiac evaluation was advised but the patient and family opted for a conservative medical management considering his age and co-morbidities.
