"Completed" and "abortive" alternating Wenckebach periods occurred in a symptomatic female with calcification of the mitral annulus. These arrhythmias were attributed to transverse dissociation of the His bundle into two horizontal levels "connected in series," with 2:1 block in the "distal" level and Wenckebach periods in the "proximal" level. Intra-Hisian alternating Wenckebach periods resembled those resulting from transverse dissociation of other infra-AV nodal structures in that they are rare, usually symptomatic and require pacemaker implantation. This contrasts with the variety of rhythms resulting from transverse dissociation of the AV node which occur frequently, are not always malignant, and generally are not treated with implanted pacemakers.
在一名有症状的二尖瓣环钙化女性患者中出现了“完全性”和“顿挫性”交替性文氏周期。这些心律失常归因于希氏束横向分离为两个“串联连接”的水平，“远端”水平存在2∶1阻滞，“近端”水平存在文氏周期。希氏束内交替性文氏周期与其他房室结下结构横向分离所导致的情况相似，即它们很罕见，通常有症状，需要植入起搏器。这与房室结横向分离所导致的各种节律形成对比，后者经常发生，并不总是恶性的，一般也不用植入起搏器治疗。
