ST-Segment Elevation and Recurrent Ventricular Fibrillation: What Is the Diagnosis?
JACC. Case reports · 2025-08-20 · Case report
Abstract
We report the case of a 67-year-old man with no significant medical history who experienced sudden cardiac arrest at home. Emergency medical services performed electrical defibrillation for ventricular fibrillation and restored spontaneous circulation. A postresuscitation 12-lead electrocardiogram showed ST-elevation in the precordial leads and frequent premature ventricular contractions. Although these findings are common in daily clinical practice, an immediate detailed differential diagnosis and investigation are required. This case clearly demonstrates that in such circumstances, a broad differential diagnostic knowledge and prompt decision-making can improve the patient's prognosis.
