Patent ID: 8870736

Claim:
A method of analyzing myocardial instability of a patient, the method comprising: obtaining values for a physiological parameter representative of myocardial behavior over at least one set of cardiac cycles, wherein each set of cardiac cycles includes at least three cardiac cycles; using a microprocessor to: determine a reversal point in the physiological parameter in the set of cardiac cycles if: the value of the physiological parameter during one of the cardiac cycles of the set exceeds the value of the physiological parameter during at least one prior and at least one subsequent cardiac cycles of the set; or the value of the physiological parameter during one of the cardiac cycles of the set is less than the value of the physiological parameter during at least one prior and at least one subsequent cardiac cycles of the set; identify myocardial instability based on the reversal points in the physiological parameter; and initiate a treatment of the patient or notify the patient or a healthcare provider of a need for treatment if myocardial instability is identified.
