It was reported that there was no capture at maximum output (7.5v @ 1.5ms) and the only sensed r waves were from the external pacemaker.During the implantable icd interrogation, we turned off the external pacer in order to ascertain the underlying rhythm, and it was discovered the patient's rhythm was complete heart block.The doctor then turned the external pacer back on to maintain capture.Subsequently, he successfully inserted a temporary transvenous wire and connected it to the external temporary pacemaker, where constant capture was taking place.Patient outcome is stable.No additional information is available.
