Event Description
|
During the night between (b)(6) 2016, the patient, implanted with the subject pacemaker, was transported to the hospital due to ventricular fibrillation.The pacemaker was interrogated on (b)(6) 2016 at 08:54.Some episodes showing ventricular undersensing were recorded in the device memories.Therefore, ventricular sensitivity threshold was reprogrammed from 2mv to 1.2mv.Reportedly, ventricular tachycardia was observed on the ecg monitor in the morning.Pacemaker was interrogated again, but there was no trace of the ventricular tachycardia event which occurred in the morning in the device memories.Preliminary analysis confirmed that the pacemaker did not detect any tachycardia, most probably because events sensed by the pacemaker did not meet the criteria required for detecting and/or recording a ventricular burst episode.
