1. A method of automatically adjusting a cardiac sensing parameter, comprising:

  • sensing the occurrence of a cardiac signal;

    sampling the sensed cardiac signal to generate samples therefrom;

    determining an onset and an end of the sensed cardiac signal from the samples;

    determining the duration and amplitude of the cardiac signal; and

    verifying the stability of the cardiac signal, wherein if stability is verified, calculating the cardiac sensing parameter based on the duration and amplitude of the cardiac signal.
