Event Description
|
It was reported that this implantable pacemaker was explanted due to exhibiting oversensing and pacing inhibition with asystole of over two seconds.The device was unable to be interrogated, furthermore a safety core message was displayed.Another device was implanted instead.This device is not expected to be returned.No further adverse patient effects were reported.

Manufacturer Narrative
|
Upon receipt at our post market quality assurance laboratory, this device was thoroughly inspected and analyzed.Interrogation of the device confirmed it was operating in safety mode due to system resets.It was confirmed that brady therapy remained available.The system resets occurred during a telemetry session and caused the device to enter safety mode.Engineers determined that this device was demonstrating behavior consistent with a high internal cell impedance within the battery.The high internal impedance resulted in the system resets due to temporary high-power consumption related to telemetry attempts and subsequent reversion to safety mode operation.Boston scientific has issued a field safety notice regarding ingenio extended life (el) and cardiac resynchronization therapy pacemaker (crt-p) devices that may exhibit this behavior.This particular device is included in the high impedance in ingenio extended life (el) pacemaker and crt-p advisory population.
