A thorough evaluation of the device was performed upon receipt at our post market quality assurance laboratory.Review of device memory indicated that a charge timeout alert (45 seconds) had been recorded.The device case was opened, and visual inspection noted that one of the two high voltage (hv) capacitors was slightly swollen.The hv capacitor was analyzed, due to the extensive damage within the hv capacitor, assignable cause is undetermined but believed to be conductive foreign material, most likely anode particulate, which ultimately caused anode to cathode arcing.This capacitor issue impacted the device's ability to provide shock therapy because the hv capacitors could not be fully charged.
