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.
心率变异性（HRV）和脉搏率变异性（PRV）都是评估心脏自主神经控制的非侵入性手段。然而，从任一只手获得的 PRV 是否可以替代 HRV 尚不确定。通过线性回归分析和 Bland 和 Altman 方法，比较了从心电图信号获得的 HRV 测量值和从双手食指记录的脉搏波获得的 PRV 测量值。在正常受试者中，所有 HRV 测量值与双手相应的 PRV 测量值之间均存在高度显著的相关性（P<0.001，0.89<r<1.0）。然而，除心率和超低频率功率（ULFP）外，HRV、右 PRV 和左 PRV 之间的一些指标的一致性不足。在健康受试者中，任一手的 PRV 与 HRV 接近，但并不相同。除心率和 ULFP 外，HRV、右 PRV 和左 PRV 在正常受试者中彼此不可替代。由于 HRV 通常被认为是评估受试者自主神经调节的标准方法，因此任一手的 PRV 可能不适合评估受试者的心脏自主神经调节。
