Web1 de mar. de 2005 · SDNN reflects total variability, while rMSSD estimates high frequency variations in heart rate and primarily reflects parasympathetic activity . While SDNN and rMSSD measure fluctuations in autonomic nervous system activity, the mean R-R interval length measures the sum of parasympathetic and sympathetic influences. WebHeart rate variability (HRV) refers to the variability between successive heart beats, specifically the R-R intervals on an EKG recording. If a person has a heart rate of 60 beats per minute, the average R-R interval would be 1 second but some R-R intervals may be 0.8 seconds and others 0.12 seconds. The variability between successful beats ...
