我们研究了来自心电图（ECG）信号的心率变异性（HRV）和来自光电体积描记（PPG）信号的脉搏率变异性（PRV）之间的差异。对14名健康人进行了10分钟的指、耳光电容积描记图（PPG）和I导联心电图（ECG）记录。本研究采用时域、频域、一致性、相关系数和几何分布等分析方法对耳脉率变异性（ePRV）和指脉率变异性（fPRV）进行分析。一致性分析显示，除正常-正常（NN）范围外，PPG的ePRV或fPRV与ECG的HRV之间的一致性程度较高（Bland-Altman比值<0.1），具有中度一致性（0.1 <Bland-Altman比值<0.2）。在HRV和ePRV或fPRV参数之间发现高度显著（p<0.001）的相关性（0.97<r<1），除了在NN范围内，其中r值分别为0.92和0.85。同时，实验结果表明频域参数在统计分析中显得不足。fPRV和ePRV都是时域HRV研究的可接受替代品，特别是当ECG记录不可用且不方便时。光电容积描记术可以提供一种简单而可靠的手段来满足节律性搏动评估的要求。
We investigated the difference between heart rate variability (HRV) derived from electrocardiogramic (ECG) signals and pulse rate variability (PRV) derived from photoplethysmographic (PPG) signals. Ten-minute recordings of finger and ear photoplethysmogram (PPG) and Lead I electrocardiogram (ECG) were collected in fourteen healthy subjects. In this study, analyses accounting for time and frequency domain, agreement, correlation coefficient and geometrical distribution were utilized to process the ear pulse rate variability (ePRV) and finger pulse rate variability (fPRV). The agreement analysis showed high degree of agreement (Bland-Altman ratio ＜0.1) between ePRV or fPRV of PPG and HRV of ECG for all the parameters except the normal-to-normal (NN) range with a moderate agreement (0.1 ＜Bland-Altman ratio ＜0.2). Highly significant (p＜0.001) correlations (0.97＜r＜1) were found between HRV and ePRV or fPRV parameters except in the NN range, where the r values were 0.92 and 0.85, respectively. Also, the experimental results indicated that the frequency-domain parameters appeared inadequate in statistical analysis. Both fPRV and ePRV were acceptable surrogates for time-domain HRV study, especially when the ECG recording was unavailable and inconvenient. Photoplethysmography could offer a simple and robust means to fulfill the requirements of rhythmical pulsation assessment.
