" The Biophysical Modelling Of The Global Role Of The Cardiovascular System At Stress "

At normal state the electrocardiogram presents for each cycle a sequence of five waves denoted with the letters P, Q, R, S T. Each of these waves represents the electric activity in the various phases of the cardiac cycle. Further on, we present the modelling of the blood volume, if we administer a certain substance amount, then its passing speed will depend on its concentration, hence the volume at which it spreads in the deposit. The isotopic methods present the advantages of a more direct expression of the factors mentioned and the increased objectivity of the results compared to other functional exploration methods. A direction of priority interest is represented by the biocybernetic concept, biomathematics and system theory for the explanation of the cardiovascular control in the physical effort. Stress cardiomyopathy is a disease caused by an intense emotional or physical stress leading to reversible, rapid or severe cardiac dysfunction. Heart disease causes the greatest worries. The idea of the disease transforms the person with his own mentality in a danger state
