Ventricular arrhythmias are rare in childhood but may be associated with syncope and sudden death. This report describes 8 children with ventricular arrhythmias, 6 of whom suffered syncopal episodes. Ventricular tachycardia was documented in 5. One boy died suddenly. Complete cardiac investigation was carried out with exercise testing, Holter monitoring, echocardiography, cardiac catheterization, angiography, and electrophysiological studies. The spectrum of abnormalities related to the arrhythmias included prolapsing mitral valve, prolonged QT syndrome, sick sinus syndrome, congenital heart disease, cardiomyopathy, and idiopathic ventricular tachycardia. Exercise testing and Holter monitoring were particularly useful in documenting the arrhythmias and monitoring response to therapy.
室性心律失常在儿童期较为罕见，但可能与晕厥及猝死相关。本报告描述了8例患有室性心律失常的儿童，其中6例有晕厥发作。记录到5例室性心动过速。1名男孩突然死亡。通过运动试验、动态心电图监测、超声心动图、心导管检查、血管造影及电生理研究进行了全面的心脏检查。与心律失常相关的异常谱包括二尖瓣脱垂、QT间期延长综合征、病态窦房结综合征、先天性心脏病、心肌病及特发性室性心动过速。运动试验和动态心电图监测在记录心律失常及监测治疗反应方面特别有用。
