Exercise-induced nonsustained ventricular tachycardia: a significant marker of coronary artery disease?
Diagnostic exercise stress testing is commonly performed in patients with known or suspected cardiovascular disease. The significance of an ischemic response, manifested as significant ST-segment depression, angina pectoris, transient myocardial perfusion abnormalities, or combinations thereof, is well established. However, the diagnostic implications of exercise-induced nonsustained VT are uncertain, especially as an isolated finding. The patient had threatening ventricular arrhythmias at peak exercise without an ischemic response. Subsequent cardiac catheterization revealed significant CAD requiring percutaneous coronary intervention.
