Event Description

It was reported that the patient had open heart surgery followed by another open heart surgery approximately two weeks later.There were many stored episodes of noise and oversensing noted during the procedures, possibly due to cautery.During the most recent open heart surgery, inappropriate high voltage therapy was delivered due to oversensing and a lead integrity alert (lia) was also noted to be triggered due to the cautery which induced noise and oversensing on the right ventricular (rv) lead.The cardiac resynchronization therapy defibrillator (crt-d) and lead remain in use.No patient complications have been reported as a result of this event.
