What is Heart Rate Variability?

Heart Rate Variability and Chiropractic Care 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 disease 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 … Continue reading
