1. A computer implemented method for detecting arrhythmias in cardiac activity, comprising:
under control of one or more processors configured with specific executable instructions,
obtaining far field cardiac activity (CA) signals for one or more beats;
applying a detection process, to the CA signals, to obtain a device marker;
identifying a first feature of interest (FOI) within an analysis window of a segment of the CA signal;
calculating a difference between the first FOI and the device marker;
adjusting a feature detection window with respect to the CA signals based on the difference;
detecting a second FOI in the feature detection window over the CA signals; and
rejecting an arrhythmia detection based on the second FOI detected.
