The study presents a mathematical model of non-linear dynamics of the heart rate variability (HRV). The model is based on quantitative characteristics of pulse conduction in the heart conducting system: the delays of sinoatrial (SA) and atrioventricular (AV) pulse conduction and refractors periods of the SA and AV nodes. The model predicts heart rate disturbances in fast electric activity of the atria, increase in the delay of the AV conduction, the critical value of atrial period where transition to non-linear dynamics of the heart rate variability starts. The correlation between indexes of HRV and period of stimulation of atria for 1-contour cardiac control model has been demonstrated.
该研究提出了心率变异性(HRV)非线性动力学的数学模型。该模型基于心脏传导系统中脉冲传导的定量特征:窦房(SA)和房室(AV)脉冲传导的延迟以及SA和AV节点的不应期。该模型预测心房快速电活动中的心率紊乱、房室传导延迟增加、心房周期的临界值,在该临界值处开始向心率变异性的非线性动力学转变。已经证明了1轮廓心脏控制模型的HRV指标与心房刺激周期之间的相关性。
