摘要：

We have developed a rapid, quantitative procedure to fit the spectra of the real and imaginary part of tissue impedance, providing characteristic parameters: time constants, their distribution, and the amplitudes of associated dispersions, Based on the time course of tissue impedance during ischemia, we have derived the evolution of characteristic parameters for both myocardial and liver tissue, The similar evolution of the distribution of time constants for myocardial and liver tissue is emphasized and discussed.
