The m300 logs, ics setup and m300 patient monitor were requested back for analysis but were not available.The device analysis of the event screen shot shows the heart rate suddenly increased from 76 beats per minute (bpm) to 180 bpm, but the qrs complex shapes showed no change on lead ii or lead v.Since the beats at the time of the event are the same as the normal template built in the relearn phase, all the beats were classified as normal beats, and therefore, an svt alarm was issued (not vtach).This is consistent with normal device behavior based on the ecg arrhythmia algorithm, template, and beat classification.There is no indication of a device malfunction.
