Abstract

The parametric stability of heart rate dynamics during atrial fibrillation was estimated relative to the changes in the parameter characterizing the curvature of the atrioventricular (AV) nodal delay function via computer modeling. Heart rate dynamics parameters were studied as dependent on the number of ectopic sources functioning in the atrium during fibrillation. Heart rate stability in ciliary arrhythmia was found to decrease with increasing number of independent ectopic sources in the atrium and increasing parameter of the curvature of the AV nodal delay function.
