1. A method for analyzing a sensed physiological signal to detect pace-induced phrenic nerve stimulation, wherein the pace-induced phrenic nerve stimulation is phrenic nerve stimulation induced by cardiac paces, the method comprising:

  • sampling the sensed physiological signal during each of a plurality of cardiac cycles to provide sampled signals, wherein sampling the sensed physiological signal includes sampling the signal during a time window defined using a pace time with each of the cardiac cycles to avoid cardiac components and phrenic nerve stimulation components in the sampled signal;

    calculating a baseline level for the physiological signal using the sampled signals; and

    detecting pace-induced phrenic nerve stimulation using the sensed physiological signal and the calculated baseline level.
