It was reported that this implantable cardioverter defibrillator (icd) delivered unsuccessful anti-tachycardia pacing therapy for a polymorphic rhythm that was at a therapy zone.Afterwards, the device was charging a shock but apparently an external shock was delivered, and the rhythm was broken, therefore the icd charge was diverted due to a ventricular pace marker following.Throughout the episode there was some under sensed beats observed but therapy was not delayed due to this.Reprogramming options were discussed for this patient.The icd remains in service.No additional adverse patient effects were reported.
