Atrial fibrillation with concurrent ventricular preexcitation identifies a high-risk arrhythmic substrate and usually results in catheter ablation of the atrioventricular bypass tract. Electrocardiography can only approximate the anatomical location of an accessory pathway. Here we report a case where a bypass tract was localised to a coronary sinus aneurysm and antegrade atrioventricular conduction masked underlying atrioventricular nodal block.
伴有心室预激的心房颤动提示存在高风险心律失常基质，通常需对房室旁路进行导管消融。心电图仅能大致判断旁路的解剖位置。在此，我们报告一例旁路位于冠状窦瘤内且前传房室传导掩盖了潜在房室结阻滞的病例。
