Title: Respiratory sinus arrhythmia training system

Abstract: A biofeedback training method and apparatus to increase and reinforce the respiratory sinus arrhythmia as an outcome of a breath training technique, said apparatus comprising a physiological monitoring device that provides raw physiological data to a computer having a software program that receives and utilizes the heartbeat interbeat interval information supplied by the physiological sensors, calculates such intervals after every heartbeat, computes RSA parameters from the interbeat intervals, displays raw signal instantaneous heart rate values, calculates RSA parameters in the form of graphs, compares current values of the RSA training score with currently set threshold level to generate training feedback, provides continuous audiovisual feedback to the user to reward training attempts based on results of threshold comparisons, displays a breath pacer to induce an appropriate breathing pattern, recommended by selected breathing technique, saves interbeat intervals along with the RSA parameters into a built-in database for further review of training sessions, and permits the user to make several adjustments.
