Abstract

Rate-dependent left bundle branch block (LBBB) during general anaesthesia is rare. While it is usually a benign disorder ,it may mask the electrocardiographic diagnosis of acute myocardial infarction and ST-T pattern associated with LBBB may mistaken for those of ischemia. To the best of our knowledge there are only few case reports of rate dependent LBBB during intraoperative period in the literature. Herein, we present a case of rate-dependent left bundle branch block developed intra-operatively in a 70 years old female patient with no previous history of ischaemic heart disease and structurally normal heart.
