【摘要】：研究了心率变异性(heart rate variability,HRV)是否可以由脉率变异性(pulse rate variability,PRV)替代,以及HRV与PRV之间的定量关系.同步采集了健康青少年、老年人与心血管病人组各25人的脉搏和心电数据,并通过定量对比分析了HRV与PRV在时域、频域和非线性三个方面的特征参数.结果表明,HRV与PRV二者不是完全一致的,其中健康青少年组的全部参数(SDNN,RMSSD,PNN50,HF,LF,SD_1,SD_2,α_1,α_2,SE,CD和AE;Ratio0.2)均具有一致性,故二者在一定程度上可以互相替代分析;而老年人组和心血管病人组只有部分参数(老年:SDNN,SD_1,SD_2,α_1,α_2,CD,SE和AE;病人:SDNN,SD_2,α_1,α_2,CD和AE;Ratio0.2)具有一致性,其余参数(老年:PNN50,RMSSD,LF和HF;病人:PNN50,RMSSD,LF,HF,SD_1和SE;Ratio≥0.2)都不具有充分的一致性,故二者不可以互相替代分析.
[Abstract]:Whether heart rate variability (heart rate variability,HRV) can be replaced by pulse rate variability (pulse rate variability,PRV) and the quantitative relationship between HRV and PRV were studied. Pulse and ECG data of 25 healthy adolescents, 25 elderly and 25 cardiovascular patients were collected simultaneously, and the characteristic parameters of HRV and PRV in time domain, frequency domain and nonlinearity were compared and analyzed quantitatively. The results show that HRV and PRV are not exactly the same, and all parameters (SDNN,RMSSD,PNN50,HF,LF,SD_1,SD_2, 伪 _ 1, 伪 _ 2, SECD and AE;) of healthy adolescents are not identical. Ratio0.2 is consistent, so they can be substituted for each other to some extent, while the elderly and cardiovascular patients only have some parameters (elderly: SDNN,SD_1,SD_2, 伪 _ 1, 伪 _ 2 + CDSE and AE;). Patient: SDNN,SD_2, 伪 _ 1, 伪 _ 2 CD and AE;Ratio0.2) consistent, other parameters (elderly: PNN50,RMSSD,LF and HF; patients: PNN50,RMSSD,LF,HF,SD_1 and SE;) Ratio 鈮，
