Abstract :
Heart rate variability (HRV) provides a noninvasive means of quantifying cardiac autonomic activity. Imbalances in autonomic activity between the sympathetic and parasympathetic systems accompany a number of cardiac disorders. This paper provides new results in mathematically modeling the cardiac nervous system responsible for fluctuations in heart rate. These results clearly demonstrate the differing varieties of heart rate fluctuations over a wide range of cardiac autonomic balances as evidenced by Poincare plots of simulated data vs. actual data obtained from subjects
