Tetralogy of Fallot is the most common cyanotic heart disease. Corrective intracardiac repair has been performed for >40 years with excellent results. Nevertheless ventricular arrhythmias have consistently been reported, and sudden cardiac death is the most common cause of mortality late after repair. Programmed ventricular stimulation has been used in selected patients at many centers; however, attempts to clarify its predictive value have been limited by small patient number and relatively low event rates. The emergence of successful methods for both the prevention of arrhythmias, (including electrophysiological ablation and implantable defibrillators), has meant the identification of those at risk of even greater importance.
法洛四联症是最常见的青紫型心脏病。心内矫正修复手术已开展40多年，效果良好。然而，一直有关于室性心律失常的报道，心脏性猝死是修复术后晚期最常见的死亡原因。许多中心已在部分患者中使用程序心室刺激；然而，由于患者数量少且事件发生率相对较低，明确其预测价值的尝试受到了限制。预防心律失常的成功方法（包括电生理消融和植入式除颤器）的出现，意味着识别有更高风险的患者变得更加重要。
