Abstract:
Analysis of heart rate responses in 130 patients undergoing dobutamine stress echocardiography revealed that heart rate response at 20 microg/kg/min predicted the eventual need for atropine in chronotropically incompetent patients. Administering atropine at intermediate doses of dobutamine rather than at peak stress may reduce test duration and provide a more balanced chronotropic and inotropic stress.
