Abstract：
:Electrocardiographic manifestation mimicking the hyperacute phase of myocardial infarction and the electrical alternans of the elevated ST-segment in association with subarachnoid hemorrhage were reported in two patients with no evidence of heart disease. In both cases the ST-segment changes were transient and there were no persistent changes suggestive of underlying myocardial damage or ischemia. These findings suggested that the electrocardiographic changes were probably secondary to subarachnoid hemorrhage and not an expression of primary myocardial disease. The electrocardiographic abnormalities could be explained by altered autonomic activity to coronary arteries or directly to the myocardium.
