The device was received from the field with no telemetry and battery having reached end of service level.Attempts to interrogate the device failed due to lack of telemetry caused by low battery voltage.Following x-ray evaluation, which showed no anomaly, the pacer was cut-open and connected to an external power source which indicated high drain current.The device was tested further using thermal imaging which narrowed down to the capacitor as the source of high leakage and depletion of the battery consistent with the communication anomaly observed on the field.
