    • A method for detecting a quantitative measure of a physiologic state of a myocardium or coronary artery by detecting the extent of change of myocardial electrical impedance from a mean baseline value to provide diagnosis of the extent of ischemia, stenosis, tissue rejection, reperfusion and the effectiveness of cardioplegia . Electrodes (16,18) are attached to the myocardium (14), baseline measurements of the mean myocardial impedance are stored, and the variance of the myocardial electrical impedance and a baseline value of mean myocardial electrical impedance are computed from the baseline measurements using custom circuitry (12) and a computer (10). After a mean myocardial electrical impedance changes from a computed baseline value by at least the measured variance, the extent of change in the myocardial physiologic state is diagnosed as a continuous, smooth, function of the extent or rate of change of a periodically measured myocardial electrical impedance from the baseline value.
    • 通过从平均基线值检测心肌电阻抗的变化程度来检测心肌或冠状动脉的生理状态的定量测量的方法,以提供缺血,狭窄,组织排斥,再灌注和有效性的程度的诊断 的心脏停跳。 电极(16,18)连接到心肌(14),存储平均心肌阻抗的基线测量,并且使用定制从基线测量计算心肌电阻抗的方差和平均心肌电阻抗的基线值 电路(12)和计算机(10)。 在平均心肌电阻抗从计算基线值至少改变测量方差之后,心肌生理状态的变化程度被诊断为周期性测量的心肌电气的变化程度或速率的连续,平滑的功能 阻抗从基线值。
