Event or Problem Description
It was reported that the cardiac resynchronization therapy pacemaker (crt-p) had premature battery depletion.It was also noted that the right atrial (ra) lead exhibited undersensing and had an atrial lead position check failure.It was further noted that the battery depletion was expected based on the ra lead, right ventricular (rv) lead, and left ventricular (lv) lead impedance drops and increased outputs on both ra and rv leads.T-wave oversensing (twos) was observed on the atrial channel.While in office, the ra lead was reprogrammed, which included turning off the atrial lead position check due to chronic status of the lead and the previous alert.No further action was planned and the patient will continue to be monitored.The device and all three leads remain in use.No patient complications have been reported as a result of this event.
