ST-segment elevation and QRS widening occurred about 1 min after carotid sinus stimulation (a) and resolved spontaneously without treatment (b). At the end of the operation, marked ST-segment elevation occurred, and returned to baseline after i.v. infusion of lidocaine 1%, 80 mg. The duration of this episode was 5 min (c).

Coronary angiogram and ECG supporting the diagnosis of variant angina. (a) Coronary angiogram showed diffuse, slight narrowing of the distal bed of posterolateral branch of the right coronary artery. (b) The posterolateral branch of the right coronary artery was occluded totally after i.v. ergonovine, and (c) the spasm was relieved after intracoronary nitroglycerine. (d) The patient experienced chest pain with ST-segment elevation in leads II, III and aVF, and reciprocal ST-segment depression in leads I and aVL.
