Abstract : The heart rhythm is beneath the supervision of the nodal tissue which encompasses the Keith flack node, the Aschoff Tawara node and the Hiss bundle. Keith flack node, in the right auricle wall emits an impetus that propagates. In 1/10 of second the influx reaches the Aschoff Tawara node and after another 1/10 of second, the influx reaches the Hiss bundle leading it to the ventricles in order to entail their contractions. Can it be said that this impetus from Keith flack node has undergone an exergetic loss when arrived to ventricles contractions step? No answer for the moment. But having seen the time scale of transfer it can be approximated that the influx is integrally transmitted. One of its parts has been used for the myocarde electrical activity and one part for the blood motion. This last part is concerned in this paper. The total massic differential enthalpy has been issued as a prominent parameter making possible the assessment of the Keith flack impetus. In this paper, thermoexergetic parameters such as work power [E ̇^+], effective work power [E ̇_e^+],exergetic loss [L ̇], exergetic yield [η_ex] and massic entropy variation [∆s] have been determined.The study has been performed on healthy persons, men and women, of Democratic Republic of Congo. The sample of 20.000 cases of healthy persons whose age varies between 13-73 years has been investigated. The blood pressure measurements and calculations are our methodology of work. The figures have been plotted by means of origin 8 program. In each cross section of life, the exergetic yield and the massic entropy variation have been found constant while the work power, the effective work power and the exergetic loss are increasing with the increasing cardiac frequency. Also the small change of those parameters with the age has been noted as well for the men as for the women subtitle. KUNYIMA formula has been proposed to calculate the work power and its values are expressed in Kys (KUNYIMA units). Results are hereby discussed.
