*Akhila Ann Cherian, Dr. Sara Kurien K. and Dr. Prakash Krishnan
ABSTRACT
Atenolol is a second-generation β-blocker that reduces heart rate and blood pressure and decreases myocardial contractility. It is an FDA-approved drug indicated in management of hypertension, angina pectoris, and acute myocardial infarction. The most common side effect associated with Atenolol is fatigue followed by hypotension, bradycardia, cold extremities, depression, diarrhea, vertigo, dizziness and rarely, second/third degree AV block. So far only 45 cases of Atenolol induced AV block have been reported. Here we present the case of a 79-year-old male with Second-degree Atrio-Ventricular block while on treatment with Atenolol for therapeutic management of hypertension.
Keywords: Atenolol, AV block, Ambulatory ECG, Mobitz type II block.
