The device was received from the field with battery voltage above elective replacement level.The pacer was analyzed under electrical and mechanical conditions with normal results.Additionally, telemetry test under field settings indicated no anomaly and multiple interrogations during the analysis did not find any interrogation anomaly.The reported event of failure to interrogate was not confirmed.The interrogation issue noted in the field is consistent with exposure of the device to electrocautery.Longevity assessment was performed, and the device was in the normal range of operation with appropriate remaining longevity.
