ABSTRACT
A 38-year-old man presented with typical squeezing-type anterior chest pain. An initial electrocardiogram (ECG) showed prominent ST-segment elevation (V1-V4 lead, 3 mm). Suddenly, the patient fell unconscious and had no pulse. At that time, the ECG showed polymorphic ventricular fibrillation (VT). After direct current (DC) cardioversion, the patient regained vital signs and defibrillation converted the VT into an accelerated idioventricular rhythm with resolution of the ST-segment elevation. The patient was referred to our hospital for close observation and further evaluation. At our hospital, an ECG showed normal sinus rhythms and cardiac enzymes were within normal limits. We diagnosed the patient with variant angina rather than ST elevation myocardial infarction (STEMI), because his clinical manifestations were quite distinct; ST-segment elevations disappeared slowly at the reperfusion stage. However, the patient's final diagnosis was STEMI because coronary angiography showed severe eccentric tubular stenosis (85%) with remnant thrombus in the middle left anterior descending artery. Defibrillation likely removed the thrombus, which led to STEMI.
