title: [Modeling the effect of rhythm on the strength of myocardial contraction].
abstract: A linear three-pool model of rhythm-inotropic phenomena in the cardiac muscle is proposed. Dynamics of accumulation and liberation of calcium from intracellular pools is described by differential equations. It has been shown by numerical experiments that rhythm-inotropic phenomena in the normal cardiac muscle and under cardiac insufficiency can be described qualitatively in terms of the concept on calcium recirculation in intracellular pools.
