1. A method comprising:

  • detecting a posture transition of a patient;

    monitoring autonomic nervous system activity of the patient for a defined period in response to detecting the posture transition;

    determining a baseline indicator of the autonomic nervous system activity during the monitoring period;

    following the monitoring period, continuing monitoring of the autonomic nervous system activity of the patient during a subsequent period;

    determining, based upon monitoring during the subsequent period, an indicator of an autonomic nervous system activity of the patient;

    comparing the indicator based upon monitoring during the subsequent period to the baseline indicator; and

    estimating a probability that the patient will experience vasovagal syncope as a function of the comparing step.
