*A study<ref>https://www.jstage.jst.go.jp/article/biomedres/29/5/29_5_245/_article</ref> conducted on heart rate variability during meditation which emphasizes inward attention, investigated two groups of subjects: 10 experimental subjects with Zen meditation experience and 10 control subjects without any meditation experience. The results of the study were as follows:
**Analysis of the heart rate variability both in time and frequency domains revealed common as well as different effects on the heart rate variability between inward-attention meditation and normal rest. 
**The most significant difference of effects between the two groups were the decrease of low frequency/high frequency ratio and low frequency norm, as well as the increase of high frequency norm. 
***This implied the advantage of a sympathovagal balance toward parasympathetic activity. 
**Regular oscillating rhythms too, were observed of the heart rate while the low frequency/high frequency ratio was not large under meditation. 
*Additionally,
**The findings of the study indicate that regular oscillations of heart rate signal could appear in the high-frequency band of the heart rate variability with smaller amplitude.
**Inward attention meditation practice appears to push the sympathovagal balance to parasympathetic predominance and induce oscillations that are regular in heart rate. 
**The results of the study seem to support health benefits in meditation wherein the sympathovagal balance toward sympathetic activity due to stress or disease.
