Acute ST-segment elevation myocardial infarction (STEMI) occurs due to occlusion of one or more coronary arteries causing myocardial injury. It is a medical emergency and requires prompt diagnosis and intervention. Transient ST-segment elevation can occur due to coronary vasospasm, and their association has been reported with subarachnoid hemorrhage. We present a distinct case of ST-segment elevations in inferior leads with reciprocal ST-depressions in lateral leads, indicating STEMI that leads to complete heart block and ventricular fibrillation cardiac arrest in a patient with subarachnoid hemorrhage. The coronary angiogram was negative for any obstructive coronary artery disease.
