A model of the cardiac conduction system is considered. The model provides an insight into the electrical processes in the myocardium under normal and pathological conditions. The model takes into account the involvement of the atria in generating the sinus rhythm of the heart and the sinus rhythm disorders in arrhythmia. The role of the atrioventricular node in reducing the risks associated with the cardiac conduction disorders in the sinoatrial region is considered. This includes frequency filtering of impulses transmitted from atria to ventricles and the activity of the second-order automatism node. The model can include units for simulating third- and fourth-order automatism nodes and a source of impulses that can cause premature ventricular contraction.
