摘要

wenckebach -心动过速时周期性VA延长和HH间期突然缩短表明(i)上共同通路逆行阻滞，通过上缓慢通路表现逆行心房激活，（ii）逆行心房激活通过快速通路顺行返回His束。

A spontaneous or pacing-induced transition from slow-fast atrioventricular nodal reentrant tachycardia to fast-slow type using a superior slow pathway

Wenckebach-periodic VA prolongation and abrupt shortening of HH interval during tachycardia indicate (i) a retrograde block at the upper common pathway that manifested a retrograde atrial activation via the superior slow pathway, and (ii) an antegrade return of a retrograde atrial activation to His bundle via the fast pathway.
