Abstract:	Our study is a correlation study between a well known cardiac parameter, the ejection fraction, and the new defined paramenter the mechanical impedance. We are trying to demonstrate that the new defined parameter Za can be used to caraterize the functioning of the heart. If there is a corellation between the two parameters than Za can become a new parameter that can be used in diagnosing heart deseases. Obvious the new defined parameter Za need more studies until he can become a real diagnosing parameter but what we can say is that he have a big potential in caracterizing heart desease. We foud out that the correlation factor between Za and EF is 0.96 in total which represent a strong link between the variation of the two parameters. The analises was done on a serie of 2977 patients, women’s and men’s and we had done the the correlation separate by gender and also on total.
