A computerized respiratory sinus arrhythmia program for the non-invasive assessment of parasympathetic activity.
The availability of sophisticated signal analysis methods based on the use of micro-computers allows an accurate non-invasive assessment of parasympathetic activity, through the measurement of the respiratory sinus arrhythmia. The program described herein is in Quickbasic and consists of 5 programs. At termination of the computer analysis the results are printed which include the average heart rate for inspiration and expiration, the averaged standard deviation of the R-R intervals for inspiration and expiration, and the R-R interval in milliseconds averaged for all inspiratory and expiratory cycles. Significant correlations were obtained when comparing the analyses of the computerized program with a manual method.
