A non invasive method for cardiac diseases quantification is described in this paper. The method uses discriminant analysis of temporal, spectral and cepstral parameters computed from the plethismographic signal which represents an impedance variation in explored thoracic region at the level of the ascending aorta. Two kinds of cardiac diseases were explored: mitral stenosis (MT) and aortic stenosis (A.S). Fifteen parameters were identified for cardiac discrimination (Five temporal parameters, three spectral and seven cepstral). Results are compared to those of Echo-Doppler method which revealed a correlation coefficient of R=0.761 representing a statistical significance of P< 0.001.

Keywords: Electrical plethismography, impedance cardiography, mitral stenosis (MT), aortic stenosis (A.S)
