1. A computer implemented method, comprising:
under control of one or more processors, within an implantable cardiac monitor (ICM) to be implanted subcutaneously, configured with specific executable instructions,
sensing, between two or more electrodes, far field, subcutaneous electrical cardiac activity (CA) signals generated by a heart for multiple cardiac cycles, the two or more electrodes configured to be located at a site outside of a heart on or adjacent a housing of the ICM;
detecting whether an event of interest is present in the CA signals;
filtering the CA signals to obtain respiration data indicative of a respiration pattern; and
analyzing the respiration data for respiration induced under detection of the event of interest from the CA signals.
