1. A method performed by at least one of a processor or controller of a device or system, the method comprising:
obtaining a list of sensed intervals associated with an arrhythmic episode detection;
identifying one or more true R-R intervals within the list of sensed intervals;
removing the one or more true R-R intervals, from the list of sensed intervals, to thereby produce a remaining list of sensed intervals;
classifying some individual intervals, in the remaining list of sensed intervals, as a short interval to thereby produce a list of short intervals;
using multiple discrimination criteria to classify one or more intervals in the list of short intervals as over-sensed R-R intervals; and
determining whether the arrhythmic episode detection was a false positive detection, based on results of the using the multiple discrimination criteria to classify one or more intervals in the list of short intervals as over-sensed R-R intervals.
