BACKGROUND
A 25-year-old woman experienced three episodes of syncope over the course of 2 years. The attacks all occurred just after she had sat down, and two were accompanied by convulsions. She had no obvious prodromes and no personal or family history of cardiovascular disease.
INVESTIGATIONS
Electrocardiography, chest radiography, echocardiography, cerebral and cardiac MRI, electroencephalography, 24 h Holter monitoring, electrophysiological study with drug provocation testing and heart-rate variability analysis.
DIAGNOSIS
Vagally mediated ventricular fibrillation initiated by premature ventricular complexes arising from the right ventricular outflow tract.
MANAGEMENT
Catheter ablation was performed at the right ventricular outflow tract and an implantable cardioverter-defibrillator was fitted.
背景
一名25岁女性在2年时间里经历了3次晕厥发作。所有发作均在她坐下后立即发生，其中两次伴有抽搐。她没有明显的前驱症状，也没有心血管疾病的个人史或家族史。
检查
心电图、胸部X线、超声心动图、脑部和心脏磁共振成像、脑电图、24小时动态心电图监测、药物激发试验的电生理研究以及心率变异性分析。
诊断
由右心室流出道室性早搏引发的迷走神经介导的心室颤动。
治疗
在右心室流出道进行了导管消融，并植入了植入式心脏复律除颤器。
