| Research Abstract |
Heart rate variability (HRV) has been widely used as an index of human autonomic nervous activity. Recently, numerous noninvasive attempts to estimate the autonomic balance have been conducted using spectral analysis of HRV. HRV is composed of two major components: Respiratory sinus arrhythmia (RSA) and Mayer wave related sinus arrhythmia (MWSA). RSA is variation of heart rate accompanied with respiration and mediated by parasympathetic nerves. MWSA is in relation to periodical blood pressure variation (Mayer wave) and is mediated by both sympathetic and parasympathetic nerves. In many studies on HRV, the spectral powers of MWSA and RSA are named as LF (low frequency) and HF (high frequency) respectively. The ratio of LF/HF has been used as an index of human autonomic balance. However, the procedures for HRV measurements have not been validated. Especially, effect of the change of respiration should be considered which could affect not only on HF component, but also on LF component. We have developed three kind of computer software for the HRV measurement and analysis (real-time HRV monitoring system, analysis system for POLAR S-810 and long term HRV monitoring) with special reference to the effect of respiration. The characteristics and technical details of the systems and sample results of the measurement are shown in this report.
