Retrograde Wenckebach phenomenon, occurring between the paced ventricles and the atria, developed in a patient with acute anterior myocardial infarction and ventricular dysfunction. This report has summarized previous investigations on ventriculoatrial conduction and their application to this case. With paced ventricular beats, VA conduction may occur but VA conduction time is longer than AV conduction time at similar heart rates. Progressive degrees of VA block develop at the AV node as the heart rate speeds. VA conduction may occur in the presence of complete AV block. Concealed VA conduction to the AV node supresses AV conduction.
一名急性前壁心肌梗死合并心室功能障碍的患者出现了逆向文氏现象，该现象发生在心室起搏与心房之间。本报告总结了先前关于室房传导的研究及其在该病例中的应用。在心室起搏时，室房传导可能发生，但在相似心率下室房传导时间长于房室传导时间。随着心率加快，房室结会出现逐渐加重的室房阻滞。在完全性房室传导阻滞的情况下，室房传导仍可能发生。隐匿性室房传导至房室结会抑制房室传导。
