1. A PPG system configured to determine cardiac stability of a patient, the PPG system comprising:

  • a PPG sensor configured to be secured to an anatomical portion of the patient, wherein the PPG sensor is configured to sense a physiological characteristic of the patient; and

    a monitor operatively connected to the PPG sensor, the monitor receiving a PPG signal from the PPG sensor, the monitor comprising a cardiac stability analysis module configured to determine an amplitude variance of the PPG signal over a predetermined time period and configured to determine a pulse period variance of the PPG signal over the time period, the cardiac stability analysis module configured to determine cardiac stability as a function of the amplitude variance and the pulse period variance.
