Progressive bradycardia with increasing doses of dobutamine leading to stress echo interruption.
Dobutamine stress testing is an important non-invasive method for evaluating patients with known or suspected coronary artery disease who are unable to adequately exercise. We present a case of a paradoxical, progressive bradycardia occurring with increasing doses of dobutamine that resulted in stress test interruption.
