Abstract:
1. A method for detecting a quantitative measure of a pathophysiologic state of a human myocardium or coronary artery of an individual, the method comprising: a) attaching at least one electrode pair to the myocardium; b) recording baseline measurements of the mean myocardial electrical impedance and computing the variance of the myocardial electrical impedance between each electrode pair; c) computing a baseline value of mean myocardial electrical impedance from the baseline measurements; d) periodically measuring mean myocardial electrical impedance values between each electrode pair over an interval of time and storing data representing the impedance values as a function of time; and e) after the mean myocardial electrical impedance changes from the computed baseline value by at least the measured variance, diagnosing the extent of change in the myocardial pathophysiologic state as a continuous, smooth, function of the extent of change, or rate of change, of the periodically measured myocardial electrical impedance from the baseline value.
