MAUDE Adverse Event Report: MEDTRONIC NEUROMODULATION CAPSURE EPICARDIAL LEAD; PERMANENT PACEMAKER ELECTRODE

Model Number	4968-35
Medical Device Problem Codes	Signal Artifact/Noise (1036); High impedance (1291); Over-Sensing (1438); Under-Sensing (1661); Decreased Sensitivity (2534)
Health Effect - Clinical Code	Dyspnea (1816)
Date of Event	02/09/2026
Type of Reportable Event	Serious Injury
Event or Problem Description
It was reported that the patient experienced shortness of breath.A lead alert triggered on the right atrial (ra) lead due to undefined high pacing impedance, far field r-wave (ffrw) oversensing, and noise.In addition, there was atrial undersensing with decreased amplitudes.Reprogramming was performed to change the device to single chamber fixed rate.The ra lead remains in use.No further patient complications have been reported as a result of this event.
