Additional information: h3 and h6.The reported field event of patient notifier anomaly was confirmed in the lab.Interrogation of the device revealed that the device was above the elective replacement indicator (eri) when received for analysis.A longevity calculation was performed based upon programmed settings and usage data in the device image.The calculations revealed that the battery depletion was normal up to the event date.The device's functionality was bench tested regarding telemetry, pacing, sensing, impedance, high voltage (hv) output, and hv shock.The patient notifier failed to vibrate during the bench test.The cause of the anomaly was due to a patient notifier component failure, however, the cause of the failed patient notifier component could not be conclusively undetermined.
