Abstract:
A method for on-line real-time estimation of myocardial contractility parameters at the isovolumetric period of the left ventricular pressure wave form using Maxwell mode of cardiac muscle is described. After simplifing the mathematical mode., we presented a new technique to calculate the Vmax using 1/Vce versus p linear regression, A measuring system based on IBM-PC/XT microcomputer was developed as well. The system is employed in physiological experiments for evaluation of myocardial contractility under control condi- tions, as well as after drug administration.
