| Abstract: | The study of the blood circulation inside the heart by using the classical physics concepts can offer a more reliable view on the mechanism of blood pumping. We had defined, calculate and analyze the mechanical impedance that blood as a fluid have to overpass on entering the aorta ring. We had compared the variation of the mechanical impedance and E /A ratio by gender and age This analyses results allows us to say that the mechanical impedance can be used as a cardiac parameter. A general decrease with age is observed on the mechanical impedance, especially for women’s. Our study is opening the gate for more biophysical studies that can be done on heart pumping mechanism. |
