Progressive bradycardia with increasing doses of dobutamine leading to stress echo interruption.

چکیده
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.

CARDIOVASCULAR MEDICINE Safety and cardiac chronotropic responsiveness to the early injection of atropine during dobutamine stress echocardiography in the elderly
Objective: To determine the safety and cardiac chronotropic responsiveness to early atropine dobutamine stress echocardiography (DSE) in the elderly. Design: Retrospective study of 258 patients > 70 years who underwent early atropine DSE and 290 patients> 70 years who underwent conventional DSE. In the early atropine protocol, atropine was started at 20 mg/kg/min of dobutamine if heart rate was...
