[A case of coronary spasm during general anesthesia successfully treated with nitroglycerin and verapamil].

We had a patient without history of angina, who repetitively showed transient elevation of ST-segment during general anesthesia. Coronary spasm was suspected, but no triggering factors could be detected; the spasm being observed under deep and stable anesthesia and at this point no surgical stimulations were interposed. It was treated successfully with intravenous administrations of nitroglycerin and verapamil and no further elevations of ST-segment could be observed.
