Device was received at eri.Analysis of rco records indicates that rate responsive pacing feature was enabled, and atrial pacing demand increased from feb, 2020 to sep, 2020.When automatic settings are programmed, such as rate responsive pacing feature, the device would adjust itself to accommodate the patient¿s needs for pacing and thus affects the estimated longevity of device.Analysis of device was performed, did not find any anomalies.Longevity assessment was performed and device¿s implanted duration exceeded projected longevity and is considered normal battery depletion.Customer complaint of premature battery depletion, pacemaker found in back-up mode and incorrect measurement was not confirmed.
