Model Number DDMB1D4

Device Problems Signal Artifact/Noise (1036); Electromagnetic Interference (1194); High impedance (1291); Over-Sensing (1438); Device-Device Incompatibility (2919); Impedance Problem (2950)

Patient Problem No Clinical Signs, Symptoms or Conditions (4582)

Event Date 03/14/2023

Event Type  Injury  

Event Description

It was reported that post operatively the right atrial (ra) lead exhibited oversensing.Approximately one month after implant the ra lead exhibited undefined high impedance.It was noted that the lead had been inactivated, however it was later reported that the lead had been revised due to a suspected connection issue.After the lead revision noise was still visible when the patient moved and took deep respirations.The physician continued to monitor the lead at that time.It was further reported that a few weeks post revision atrial tachycardia/atrial fibrillation (at/af) episodes continued to show nonphysiologic noise.The physician suspected a ¿bandpass filter¿ issue with the implantable cardioverter defibrillator (icd).Episodes were reviewed by qualified technical personnel who indicated that the noise and variable impedance measurements were consistent with lead fracture.The ra lead and icd remain in use.No patient complications have been reported as a result of this event.
