A patient presented with incessant supraventricular tachycardia due to a concealed accessory pathway. The His bundle electrocardiogram showed a large discrete accessory pathway potential following ventricular activation and resulting in retrograde atrial activation. Percutaneous catheter ablation in the region of the accessory pathway potential left nodal conduction intact but prevented retrograde activation of the atria. Symptomatic tachycardia has not recurred. Direct endocardial recording of accessory pathway potentials is rare but may offer the opportunity for catheter ablation.
一名患者因隐匿性旁路出现持续性室上性心动过速。希氏束心电图显示心室激动后有一个大的离散旁路电位，导致心房逆向激动。在旁路电位区域进行经皮导管消融，保留了节点传导，但阻止了心房的逆向激动。症状性心动过速未再复发。直接心内膜记录旁路电位很少见，但可能为导管消融提供机会。
