Abstract
Ventricular fibrillation (VF) is usually sustained, and it typically results in death unless electrical defibrillation is successfully performed within minutes. Although VF has been reported to spontaneously occur in vivo in some animal models and a few cases of self-terminating VF have been documented in clinical practice, no such case has been previously reported involving out-of-hospital emergency medical service(EMS) personnel. We report a case of self-terminating VF due to ST segment elevation myocardial infarction that was documented by continuous electrocardiogram (ECG) strip monitoring. A 70-year-old woman was transported to the emergency department by EMS due to chest discomfort. The EMS personnel monitored her by ECG using an automated external defibrillator with a 3-limb lead. During transport, she developed VF, which persisted for 43 seconds. Chest compression and defibrillation were not applied. The VF self-terminated, after which the patient promptly awoke. Emergency coronary angiography was performed,and a total occlusion of the middle left circumflex coronary artery was treated by percutaneous coronary intervention. Since then, no symptomatic arrhythmia or ST-segment change was detected by continuous ECG monitoring. The patient was discharged home without any sequelae on the fourth hospital day.
