Manufacturer Narrative

This investigation will be updated should further pertinent information be provided.

Event Description

It was reported that this cardiac resynchronization therapy pacemaker (crt-p) triggered safety mode.The device changed polarity due to this mode change.The crt-p oversensed noise which resulted in pacing inhibition.Also, telemetry issues were experienced.The device has been explanted due to premature battery depletion and has been returned for analysis.No additional adverse patient effects were reported.

Manufacturer Narrative

This investigation will be updated should further pertinent information be provided.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.
