Abstract :
The dynamic compliance model is generalised to study the chemical energy needed to change LV stiffness during contraction. The resulting model is a two-port with each port acting capacitivefy but in different energy domains. On one side a chemical capacitor stores the energy of actin-myosin coupling. On the other side a spring stores elastic potential energy. Thermodynamic couplings between the two ports create a reversible deactivalion which may explain observed experimental results on flow pukes.
