RSA wave

RSA wave

<RSA wave (breathing-related sinus arrhythmia)>

Distance shortens at the time of the intake in sync with a way of the breathing, and the heart rate becomes long at the time of the expiration. It is the high frequency (HF) ingredient which is seen when frequency analyzed a heartbeat change (R-R interval) (0.15-0.4Hz, approximately four seconds period). In addition, I may be considered to be the index of the parasympathetic nerve function because I am affected by parasympathetic nerve activity (amplification factor).

(I appear for the heartbeat change only when parasympathetic nerve does it sthenia (activation))
