| 1. A method for detecting atrial tachyarrhythmia, comprising:
detecting a plurality of A-A intervals;
selecting A-A intervals from the plurality of A-A intervals based at least in part on one or more events occurring between
consecutively sensed atrial depolarizations of the A-A intervals; and
using the selected A-A intervals to detect atrial tachyarrhythmia;
wherein selecting the A-A intervals comprises:
determining if a particular A-A interval is a qualified A-A interval, comprising:
determining that the particular A-A interval is a qualified A-A interval if a duration of the particular A-A interval falls
outside a predetermined duration range; and
determining that the particular A-A interval is a qualified A-A interval based on events occurring between consecutively sensed
atrial depolarizations of the particular A-A interval if the duration of the particular A-A interval falls within the predetermined
duration range; and
wherein using the selected interval comprises using the qualified A-A interval to detect atrial tachyarrhythmia.
