[Substantiated diagnostic properties of two-component analysis of rheogram]

The paper presents a conclusive basis applicable to the parameters of two-component analysis of biosignals of the pulse filling of the rheogram type conditioning the parameters' specific use. A new original rheographic parameter is suggested for the examined zone of vascular filling--local fraction of cardiac output. A verbal model of general hemodynamic pulse filling developed by the author previously and specified within the present cases study has been used for the purpose. The model was constructed as a specific description of the working cardiovascular system during cardiac cycles, which is based on the two-phase cardiac function, with respect to the active heart work both in the systolic and diastolic phases of the cardiac cycle.
