摘要：

A new approach for monitoring myocardium edema is introduced. It utilizes electrical impedance spectroscopy (EIS) to characterize edema tissue. The system has been tested on an isolated pig heart to distinguish the edema from non-edema tissue by a decrease of impedance for edema. The impedance reduction for left ventricular was 10 Omega at 100 kHz. The algorithm used for the demodulation in the developed EIS system is based on Goertz el filter which is utilized to replace the traditional coherent demodulation technique. Multisine excitation with 16 tones in the frequency range up to 1 MHz with more than 1000 samples was used for the measurements.
