Abstract
A Wenckebach periodicity at the mitral isthmus lesion has rarely been
reported.
We described a case presenting
conduction recovery with Wenckebach periodicity at the mitral isthmus
lesion after achieving the posterior mitral isthmus block. These
findings demonstrate an early reconnection of mitral isthmus lesion, and
an arrhythmogenic substrate that can lead to development of reentrant
tachycardia, that is, peri-mitral atrial flutter.
