Intracellular calcium plays a major role in the electromechanical coupling in cardiac venrticular cells and in the action potential formation process in heart pacemaker cells. Calcium sparks are elementary events of the calcium release from sarcoplas

A regular rhythm of the mechanical contraction of the heart is formed in the so-called sinoatrial node (SAN) of the heart. In the current paper we introduce a mathematical model of the SAN cell functionality paying particular attention to calcium act

Here we introduce the results of the computer simulations on the study of age-associated abnormalities of the Ca2+ release unit functioning in the sinoatrial node cells. We simulated the decrease of sarco/endoplasmic reticulum Ca2+- ATPase activity a

Here we introduce results of a mathematical modeling of calcium sparks in cardiac cells. We developed a model of the calcium release unit which includes a single sarcoplasmic reticulum (SR) lumen, a regular 9×9 cluster of RyRs and a dyadic space. 2D

We studied the effects of intracellular calcium dynamics on the spontaneous activity of the pacemaker cells using mathematical modeling. We compared the responses to the suppression of L-type calcium currents in several models of the electrical activ

The temperature effect on cardiac ryanodine receptor (RyR) function has been studied within the electron-conformational (EC) model. It’s shown that a simple EC model with an Arrhenius-like temperature dependence of the “internal” and “externa

Spontaneous local calcium releases (sparks) from sarcoplasmic reticulum (SR) in heart cell were modeled. We solved two-dimensional problem of Ca2+ diffusion along the dyadic space and “domino-like” activation of ryanodine receptors (RyRs) on the

An integrative model of the calcium dynamics in cardiac pacemaker cells is developed taking into account a synergetic effect of the interaction between an outer membrane oscillator and an intracellular calcium oscillator ("membrane and Ca(2+)-clock")
