What is Heart Rate Variability?

Heart rate variability and chiropractic. The timing between heart beats should vary beat-to-beat. That is called heart rate variability (HRV). The more HRV, the greater a person’s health. Low HRV has been linked to physical and emotional dis-ease or body malfunction.
Analysis of the beat-to-beat intervals (heart rate variability) has been used to evaluate the nervous system balance between the sympathetic and parasympathetic divisions. Analysis of beat-to- beat variability is a simple, non-invasive technique to evaluate autonomic dysfunction and may be a tool to assess the changes in autonomic activity associated with the reduction and correction of vertebral subluxations. A search of the relevant literature found that some controlled studies suggest that very thing: chiropractic care may improve heart rate variability in a positive way – meaning that nervous system function improves.
The author writes, “Vertebral subluxations may result in altered autonomic nervous system activity. Heart rate variability is a reliable and valid tool that may be used to assess the changes in autonomic activity associated with the reduction and correction of vertebral subluxations.” (1)
This is a tool we use in our office to determine how well your body is handling stress.  Some of the things that improve it are regular chiropractic care, yoga, meditation and tai chi.
