Comparison of Heart Rate Variability and Pulse Rate Variability of Respiratory Control
Heart rate variability (HRV) can be applied to observe the autonomic nervous system activity of human beings. With the development of wearable device technology, PPG signal is often applied to measure pulse rate, and furthermore to analyze the pulse rate variability (PRV), which is considered to be equivalent to HRV. However, regular heart rate will be affected by breath volume and breath rate that causes different results when HRV and PRV are measured in different situations. This paper presents a study based on the characteristics of the respiratory sinus arrhythmia (RSA), the heart rate and tide volume of breath and the variabilities from PPG and ECG which were measured by PSG simultaneously. Furthermore, according to the measurement of PTT based on PPG and ECG signals, the characteristics of peripheral arteries were evaluated. From the results, it was found that the significance (p < 0.05) is shown between HRV and PRV when normal young groups are controlled at different tide volume of breath. No significance is shown on the PRV obtained from four limbs. In summary, the PRV and HRV show different characteristics at different breath controls. There are no differences between each PRV when PPG signals are obtained from four limbs.
