1. A cardiac monitor for determining the cardiac condition of a patient comprising:

  • a sensor that senses the intrinsic activity of a patient'"'"'s heart and generates a corresponding sensed signal;

    an interval detector that detects an interval associated with a cardiac cycle based on said sensed signal;

    a waveform factor detector that detects a waveform factor from said sensed signal, said waveform factor being a function of a ratio of a mean value of said signal during said cardiac cycle and a peak value of said signal during said interval; and

    a first comparator that compares said waveform factor to a threshold and generates a corresponding for first output indicative of the patient'"'"'s cardiac condition.
