Claim:
1. A method of detecting increased sympathetic activity indicative of a physiological abnormality, comprising: measuring, from a patient sensor, a quantifiable characteristic of a patient; quantifying, with a processor, a chaos of the quantifiable characteristic, wherein the quantified chaos comprises at least one of a chaos-like behavior or a non-linear dynamics relationship of the quantifiable characteristic; identifying, with the processor, an increasing chaos in accordance with the quantified chaos; identifying, with the processor, a non-increasing parasympathetic activity in the patient; combining, with the processor, the identified increasing chaos and the identified non-increasing parasympathetic activity to determine that the identified increasing chaos is a result of the increased sympathetic activity in the patient, the combining resulting in a more accurate determination that the identified increasing chaos is a result of the increased sympathetic activity, more accurate than either the identified increasing chaos or the identified non-increasing parasympathetic activity alone; detecting, with the processor, the physiological abnormality, wherein the detected physiological abnormality is of a type detectable by the increased sympathetic activity in the patient; and generating, with the processor, a signal indicative of the detected physiological abnormality.
