title: [Computer modeling of parametric stability of heart rate dynamics during atrial fibrillation].
abstract: Parametric stability of heart rate dynamics during atrial fibrillation was estimated in relation to the change in the parameter of the curvature of delay function in the atrioventricular node. The study was conducted by the method of computer modeling. We investigated the dependence of characteristics of stability of heart rate dynamics from the number of independent ectopic sources in the atrium during fibrillation. The results show that the stability of heart rate dynamics decreases as the number of independent ectopic sources in the atrium and the parameter of the curvature of delay function in the atrioventricular node increase.
