We encountered two cases of ventricular fibrillation (VF) without overt heart disease. The first case we report is that of a 47-year-old man, and the second case is a 39-year-old man. VF occurred in the night unrelated to myocardial ischemia or myocarditis. Their basic ECGs showed normal sinus rhythm, but neither QT prolongation nor abnormal Q wave was seen. But we could see IRBBB and ST segment elevation in the V1-2 lead not only in the acute phase, but also in the chronic phase. Abnormal findings were not found in noninvasive cardiac examinations, nor in cardiac catheterization and histological examinations. In the second case, VF was induced by electrical stimulation, and Disopyramide was found to be effective for the prevention of VF. The patient in the first case died suddenly two years after his first attack. Both cases have interesting ECG findings, and it may be that they play on important role in discovering the etiology of sudden cardiac death.
我们遇到了两例无明显心脏病的心室颤动（VF）病例。我们报告的第一例是一名47岁男性，第二例是一名39岁男性。VF发生在夜间，与心肌缺血或心肌炎无关。他们的基础心电图显示窦性心律正常，但未见QT延长或异常Q波。但我们不仅在急性期，而且在慢性期都能在V1 - 2导联看到不完全性右束支传导阻滞（IRBBB）和ST段抬高。无创心脏检查、心脏导管检查及组织学检查均未发现异常。在第二例中，VF由电刺激诱发，发现丙吡胺对预防VF有效。第一例患者在首次发作两年后突然死亡。两例均有有趣的心电图表现，可能对发现心源性猝死的病因起着重要作用。
