Results: Heart Rate Variability Analysis in the Acupuncture Clinic: Correlation with Clinical Outcomes

Results

nIt is feasible to evaluate HRV in the acupuncture clinic both by nonlinear and linear measurements. The total calculation time is 7 minutes.

n

nPatients who responded to their acupuncture treatment tended to exhibit a decrease in their LFR/HFR ratio from segment “a” to segment “b”, an increase in their SD1/SD2, and an increase in their Samp En: all of these trends indicating a decrease in their stress response

n

nNon-responders, or patients who were aggravated by a particular treatment tended to show no change or an increase in their LFR/HFR from minute and a decrease in their SD1/SD2 from the first to second time window, and an increase in their Sample Entropy

n

nThere were notable exceptions, i.e. patients who were strong responders, who did not exhibit the consistent pattern above. In these patients, Sample Entropy was the strongest predictor of successful treatment.

n

nBecause of the prevalence of artifact in heart rate monitoring, the addition of nonlinear measures gives added confidence to the measurements obtained.

nChanging the needle placement prescription and type of stimulation changed outcomes corresponding to HRV results in some cases.
