Oversensing of the wearable cardioverter defibrillator during bipolar ventricular stimulation

Wien Klin Wochenschr. 2017 Dec;129(23-24):910-912. doi: 10.1007/s00508-017-1290-z. Epub 2017 Nov 9.

Abstract

The wearable cardioverter defibrillator (WCD) is a temporary treatment option for patients with potentially reversible risk of sudden cardiac death. This case demonstrates a pitfall during WCD usage in a pacemaker-dependent patient as well as a possible solution allowing continuation of WCD therapy. Bipolar stimulation may lead to double counting of the WCD detection algorithm resulting in false alarm or inappropriate therapy.
