It was reported that the health care professional (hcp) called technical services (ts) to review this cardiac resynchronization therapy defibrillator (crt-d) system stored data due to concerns of premature battery depletion (pbd).Data analysis was performed, and evidence showed that the device battery was depleting as expected.Ts stated that the increase in power consumption appeared to be driven by the left ventricular (lv) lead current programming and low impedance measurements on the lead.Further review of the impedance measurement trending data showed a drop of the pacing impedances on the right atrial (ra) and right ventricular (rv) leads.Ts also noted that a drop in shock impedances was observed on the rv channel as well.It was noted the drop in the shock and pacing impedances remained in the normal range the hcp noted that the patient had recently been hospitalized in intensive care unit (icu) due to sepsis.At this time, the crtd remains in service.No additional adverse patient effects were reported.
