Manufacturer Narrative

The device was not returned for evaluation.The clinical event data from the event was returned and evaluated.Review of the clinical file from the reported event concluded that the device worked as designed and within the limitations of the technology.The first analysis segment was determined as fine ventricular fibrillation (shockable).The second and third segments were determined as pulseless electrical activity (pea) due to low number of peaks (not shockable).As 2 of the three segments were not shockable, the device prompted "no shock advised".The second analysis event has cpr performed during the first segment causing it to be discarded.The following two segments were determined as pea and therefore were "no shock advised".This claim has been closed as device meets specification.Analysis of reports of this type has not identified an increase in trend.
