Figure2: Decremental conduction through AP, VA interval increased from 225 to 241 msec with no change in CS sequence after RVA extrastimulation (a) Arrhythmia termination at the first fusion beat with no alteration in CS activation and perpetuation of decremental retrograde conduction through AP (b)Morady Maneuver with PPI-TCL(445-329)>115 and SA-VA(251-163)>85 consistent with AVNRT (c) Advancement and resetting after catheter induced PVC during AMC mapping(d)
Thereafter, there was V-A dissociation during RV apical pacing.
