  • Typical spontaneous Ca2+ oscillations from the computational study. From top to bottom, the three plots correspond to oscillations in cytoplasmic Ca2+, ER Ca2+, and cytoplasmic IP3. All three variables have the same frequency but different peak times (details are shown in Fig. 4). ... (A) Bifurcation diagram of Ca2+ oscillations as a function of membrane potential. Sustained Ca2+ oscillations occurred in the potential range of −70.0 to −64.9 mV, where the maximum and minimum of Ca2+ oscillations were plotted. The dashed line refers to the unstable steady state. Out of the oscillatory domain, the system evolved into a stable steady state. (B) Frequency of Ca2+ oscillations versus membrane potential. ... Dependence of Ca2+ oscillations on extracellular Ca2+ concentration. Ca2+ oscillations stopped when the extracellular Ca2+ concentration was too low or too high. From 0.1 to 1500 μM, the frequency of Ca2+ oscillations increased with a rise in extracellular Ca2+ concentration. ... Amplitude and frequency of Ca2+ oscillations versus temperature. In the temperature range of 20–37°C, both the amplitude (indicated as an asterisk) and frequency (dotted line) decreased with temperature. ... The occurrence of Ca2+ oscillation depends on the membrane potential. When the membrane potential is −64.9 mV, there is no Ca2+ oscillation. Within −70.0 to −64.9 mV, the frequency and amplitude of Ca2+ oscillations change with the membrane potential.

  • We present the code for an extended heterogeneous oscillator model of cardiac conduction system for generation of realistic 12 lead ECG waveforms. We incorporate an artificial RR-tachogram with the specific statistics of a heart rate, the frequency-domain characteristics of heart rate variability produced by Mayer and respiratory sinus arrhythmia waves, normally distributed additive noise and a baseline wander that couple the respiratory frequency. The standard 12 lead ECG is calculated by means of a weighted linear combination of atria and ventricle signals and thus can be fitted to clinical ECG of real subject. The model is capable to simulate accurately realistic ECG characteristics including local pathological phenomena accounting for biophysical properties of the human heart.
