Three minutes after the end of a negative dobutamine stress echocardio
graphy (16 mug/kg/min), a severe ischemic episode appeared, with ST-se
gment elevation in inferior leads, suggesting a spasm on a normal righ
t coronary artery. This episode was relieved by nitroglycerin. Close c
linical and electrocardiographic monitoring during and shortly after a
dobutamine stress echocardiography is mandatory.
