[Coronary artery spasm under general and epidural anesthesia].
A 66-year-old man without history of angina pectoris was scheduled for subtotal gastrectomy under epidural anesthesia supplemented with nitrous oxide and isoflurane. ECG showed an elevation of ST segment after hypotension. It passed into Wenckebach A-V block and complete A-V block. But an elevation of ST segment was relieved by raising blood pressure and it became sinus rhythm. Serum enzymes (CPK-MB, GOT and LDH) were normal after operation. It is suspected that coronary spasm was induced by hypotension and vagal stimulation under inadequate level of anesthesia, though we could not prove this arteriographically.
