Model Number DTPA2Q1

Device Problems Signal Artifact/Noise (1036); Electromagnetic Interference (1194); High impedance (1291); Misconnection (1399); Over-Sensing (1438); Impedance Problem (2950)

Event Date 11/05/2022

Event Type  Injury  

Event Description

It was reported that the patient presented approximately one week post-generator change with an itching, tingling sensation at the device pocket.An interrogation of the cardiac resynchronization therapy defibrillator (crt-d) indicated that the right ventricular (rv) lead began to exhibit impedance issues post-generator change.Pacing impedance was noted to have abruptly increased and remained high and undefined.The lead's two defibrillation coils also exhibited an increase in impedance to a high range and was then noted to consistently fluctuate.Noise or artifact was visible with pocket manipulation and patient left arm movement.  the patient was programmed to a pacing-only mode with detections turned off to avoid potential inappropriate therapy.A revision procedure was conducted where it was determined that the lead was not fully in the crt-d header.The lead was correctly connected and the lead and crt-d remain in use.The physician was not concerned about the itching, tingling sensation. no further patient complications have been reported as a result of this event.
