Retrograde Wenckebach

Sinus rhythm with concealed intranodal reentry and an episode of accelerated junctional rhythm with retrograde Wenckebach

Edit: (092823)

I would like to thank Dr. @NaokiThukishima who was able to point-out that after R4 is a PAC and not a retrograde P wave. Thus this arrhythmia was initiated by PAC leading to AVNRT. Dr. @AThomazAndrade also suggested that this could be AVNRT with a Wenckebach. Thus, the proposed ladder diagram is shown below (top diagram).
