A patient with atrioventricular (AV) nodal reentrant tachycardia assessed by electrocardiographic and electrophysiological criteria is described. During ventricular pacing, retrograde conduction was absent at the longest cycle length tested with the site of block determined to be the AV node by concealed conduction criteria. These findings localize the tachycardia circuit above the His bundle and exclude a His-atrial bypass tract as the retrograde limb of the tachycardia circuit in this patient.
描述了一名通过心电图和电生理标准评估的房室结折返性心动过速患者。在心室起搏期间，在测试的最长周期长度时无逆行传导，根据隐匿性传导标准确定阻滞部位为房室结。这些发现将心动过速环路定位于希氏束上方，并排除了希氏-心房旁路作为该患者心动过速环路逆行支的可能性。
