case_images: Delivery of 40-joule shock despite resolution of inappropriate VF sensing prior to the committed nature of therapy. Note that due to shock delivery, vigorous ventricular contraction occurs that resumes the lead chattering inappropriate sensing as VF (from top to bottom: marker channel, RV shock electrogram, and RV sense electrogram).
