Abstract

Paroxysmal second-degree A-V block occurred during exercise in a patient without prior conduction system disease. He subsequently was found to have severe triple-vessel coronary artery disease. Two episodes of block occurred early on during treadmill exercise in the presence of marked ST segment depression. While similar paroxysmal atrioventricular block is a relatively common occurrence during the transient ischemic ST elevation in Prinzmetal's angina in patients without conduction system disease, it has been described rarely in exercise induced ST depression. We believe that transient second-degree A-V block in our patient resulted from ischemia as manifested by profound ST segment depression.
