Seal plug damage causing inappropriate detection and therapy in a subcutaneous defibrillator system Anne Barnett, PA-C, Lee Eckhardt, MD, FHRS, Miguel A.

Figure 1 Intermittent noise oversensing noted on postoperative day 2 (left) and continuous noise oversensing noted on postoperative day 5 (right). The marker channel indicates that the device mislabels noise as ventricular tachyarrhythmia, leading to the inappropriate shock (lightning bolt).
