Abstract

Exercise induced complete atrioventricular block (EIAVB) is a relatively uncommon condition. This phenomenon is clinically important because it can mimic symptoms of other cardiovascular conditions and may be associated with exercise intolerance and subsequent syncope. A 76 year old man with long-standing hypertension and diabetes mellitus presented with recurrent episodes of lightheadedness and syncope with physical activity. ECG showed sinus rhythm with first degree atrioventricular block. Echocardiography did not show any valvular disease causing his symptoms. Coronoary angiographic evaluation revealed non-obstructive coronary artery disease. Because of the exertional nature of his symptoms, a symptom-limited treadmill exercise test was performed which revealed EIAVB. A permanent dual chamber pacemaker was implanted and his symptoms resolved completely.
