A 75-year-old man was admitted to our hospital for follow-up coronary angiography. Just after starting coronary angiography, his electrocardiogram showed ST-segment elevation in the V1-6, I, II, and aVF leads, and he fell into catastrophic cardiogenic shock. His left coronary arteriogram showed proximal total obstruction in the left anterior descending artery and proximal subtotal occlusion in the left circumflex artery. Because pulseless electrical activity arrest was recognized, cardiopulmonary support was started. After more than 15 minutes' cardiac massage, his blood pressure gradually returned to baseline. During the cardiogenic shock due to pulseless electrical activity arrest, neither ventricular fibrillation nor ventricular tachycardia was recognized.
