Abstract
A method and apparatus monitor myocardial ischemic events in various medical applications for providing continuous and contemporaneous information regarding, for example, modifying the amount of medication for a patient, determining response during (PTCA) balloon angioplasty, monitoring the onset of myocardial ischemic events during induction of anesthesia, determining painless myocardial ischemia in a resting patient, and monitoring the onset of myocardial ischemic during stress conditions in a patient. The method and apparatus also provide a calibration method for determining from a Resistive Index and using the resulting transformation for calculating, on a continuing basis, both systemic vascular resistance and cardiac output.
