心率变异性（HRV）和脉率变异性（PRV）都是评估心脏自主神经控制的无创手段。然而，从任何一只手获得的PRV是否可以作为HRV的替代物尚未确定。本文应用线性回归分析和Bland和Altman方法，比较了正常人由心电图信号测得的心率变异性（HRV）和由双手食指脉搏波测得的心率变异性（PRV）。双手HRV各指标与相应的PRV指标之间均存在高度相关性（P <0.001，0.89 < r < 1.0）。然而，除了心率和超低频功率（ULFP）外，HRV、右PRV和左PRV之间的配对比较在某些指标上的一致性不足。每只手的PRV与健康受试者的HRV接近，但不相同。在正常受试者中，除了心率和ULFP之外，HRV、右PRV和左PRV不是彼此的替代物。由于HRV通常被接受为用于评估受试者的自主神经调制的标准方法，因此任一只手的PRV可能不适合于评估受试者的心脏自主神经调制。
Both heart rate variability (HRV) and pulse rate variability (PRV) are noninvasive means for the assessment of autonomic nervous control of the heart. However, it is not settled whether or not the PRV obtained from either hand can be the surrogate of HRV. The HRV measures obtained from electrocardiographic signals and the PRV measures obtained from the pulse waves recorded from the index fingers of both hands were compared in normal subjects by using linear regression analysis and Bland and Altman method. Highly significant correlations (P < 0.001, 0.89 < r < 1.0) were found between all HRV measures and the corresponding PRV measures of both hands. However, there were insufficient agreements in some measures between pairwise comparisons among HRV, right PRV and left PRV except heart rate and ultra-low frequency power (ULFP). The PRV of either hand is close to, but not the same as the HRV in healthy subjects. The HRV, right PRV and left PRV are not surrogates of one another in normal subjects except heart rate and ULFP. Since HRV is generally accepted as the standard method for the assessment of the autonomic nervous modulation of a subject, the PRV of either hand may not be suitable for the assessment of the cardiac autonomic nervous modulation of the subject.
