Using His bundle recordings and ventricular stimulation retrograde conduction was studied in 57 cases of complete AV block. VA conduction was observed in 13 patients. Of the 13, 12 had AV block distal to H, and during cardiac pacing 5 of them showed a retrograde His bundle potential. In all cases the AV node-His pathway was implicated in the transmission of the retrograde impulse. There was no retrograde atrial response in the remaining patients. VA block usually occurred at the same level as AV block. Nevertheless, two cases of AV block distal to H were associated with concealed retrograde conduction which stopped within the AV node.
利用希氏束电图记录，对57例完全性房室传导阻滞患者进行了心室刺激逆行传导研究。13例患者观察到室房传导。在这13例患者中，12例希氏束远端存在房室传导阻滞，心脏起搏时其中5例显示逆行希氏束电位。所有病例中，逆行冲动的传导均涉及房室结-希氏束通路。其余患者未出现逆行心房反应。室房阻滞通常发生在与房室阻滞相同的水平。然而，有2例希氏束远端的房室传导阻滞与隐匿性逆行传导相关，该传导在房室结内终止。
