술중 급성 심근경색 소견을 나타낸 뇌지주막하 출혈 환자의 마취 1예

It is now well established that acute subarachnoid hemorrhage secondary to rupture of a cerebral aneurysm can precipitate life-threatening cardiac arrhythmia. We experienced a 60 year old patient with a subarachnoid hemorrhage (neurologic grade III) due to rupture of anterior communicating artery aneurysm who presented with such intraoperative electrocardiographic changes as ST segment elevation and T wave inversion which are hallmark of acute myocardial infarction. The operation was uneventfully ended. On the postoperative laboratory examination about suspected acute myocardial infarction, the patient was found to have normal triple enzyme study and echocardiographic finding. The electrocardiogram three days after subarachnoid hemorrhage due to cerebral aneurysm returned to normal sinus rhythm. This case suggests that this patient's electrocardiographic change simulating acute myocardial infarction is transient change due to subarachnoid hemorrhage. (Korean J Anesthesiol 1999; 36: 901∼905)
