1. A system for detecting arrhythmias in cardiac activity, comprising:
memory configured to store specific executable instructions;
one or more processors configured to execute the specific executable instructions for:
obtaining first and second far field cardiac activity (CA) data sets over primary and secondary sensing channels, respectively, in connection with a series of beats;
detecting candidate atrial features from the second CA data set;
identifying ventricular features from the first CA data set;
utilizing the ventricular features to separate beat segments within the second CA data set;
automatically iteratively analyzing the beat segments by:
overlaying an atrial activity search window with the second CA data set; and
determining whether one or more of the candidate atrial features occur within the atrial activity search window;
adjusting an atrial sensitivity profile based on whether the atrial activity search window includes the one or more of the candidate atrial features; and
detecting atrial events based on the atrial sensitivity profile.
