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.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.

Event Description

It was reported that a request for a review of this cardiac resynchronization therapy pacemaker (crt-p) episodes was made as it was unknown if the patient was having true ventricular tachycardia (vt) or oversensing.Technical services reviewed the episodes and confirmed true vt.In addition, one episode showed right ventricular (rv) undersensing and some inappropriate rv paces.This device remained in service until it was eventually explanted and replaced due to normal battery depletion.This crt-p was returned for analysis and no adverse patient effects were reported.
