.Physiolibrary.Organs.Heart.Heart .Physiolibrary.Organs.Heart.HeartCalculates hearth pumping (left and right atria and ventricles, as wel as coronary circulation). By pressure-flow connectors communicate with pulmonary and systemic circulation.
Blood volume (and pressure) distributions between
Generate average blood flow throught ventricles.
On the contrary of Tom Coleman models: coronary circulation outflows to right atrium, average blood volume in the hearth are calculated more simple (with the same results in steady state).

Effeciency by

is 25% (basal metabolism included).
Optimal values:
Left heart:
90mmHg= 12000Pa
75ml = 0.000075m3
75bpm = 1.25Hz
= 1.125 W (mechanical work)
4.5 W (total energy for 25% effeciency with basal metabolism)
1.41 W (basal metabolism)
36% motion effeciency without basal metabolism (new parameter for heart)
Right heart:
12.4mmHg=1653Pa
75ml= 0.000075m3
75bpm=1.25Hz
= 0.155 W (mechanical work)
/0.25 = 0.62 W (total energy for 25% effeciency with basal metabolism)
0.21 W (basal metabolism)
38% motion effeciency without basal metabolism (new parameter for heart)
Old estimation of heart energy balance
left: 1.67 W (const MotionCals) , 6.07 W (const HeatCals), 1.41 W(const BasalCals) = 7.74 W + 1.41 W = 9.15 W
right: 0.35 W (const MotionCals) , 1.19 W (const HeatCals), 0.21 W (const BasalCals) = 1.54 W + 0.21 W
