Heart rate variability (HRV) is a widely used measure that reflects autonomic (parasympathetic) control of the heart. HRV has been linked with attentional performance, but it is unclear to what extent resting HRV is associated with both attention and attentional maintenance. In order to address this, we calculated HRV in seventy-four young and healthy volunteers (43 men, age: 21.6 ± 2.4), who completed the D2 Test of Attention (D2), which was used to calculate an index of Concentration Performance (CP) and a measure of attention maintenance, the coefficient of variation (CV). After accounting for the effects of sex and age on HRV, there was no significant association between HRV and CP (p = .2), but a significant relationship between HRV and CV (p = .03). Overall, our study demonstrates that attention maintenance, but not attentional performance, is associated with higher resting state HRV which suggests that attentional performance from D2 subtest-to-subtest may reflect HRV's facilitation of behaviour flexibility.
心率变异性（HRV）是一种广泛使用的测量方法，反映了心脏的自主（副交感）控制。HRV 与注意力表现有关，但尚不清楚静息 HRV 在多大程度上与注意力和注意力维持都有关。为了解决这个问题，我们在 74 名年轻健康的志愿者（43 名男性，年龄：21.6±2.4）中计算了 HRV，他们完成了 D2 注意力测试（D2），该测试用于计算注意力集中性能（CP）指数和注意力维持的衡量标准，即变异系数（CV）。在考虑了性别和年龄对 HRV 的影响后，HRV 与 CP 之间没有显著关联（p=0.2），但 HRV 与 CV 之间存在显著关联（p=0.03）。总的来说，我们的研究表明，注意力维持，而不是注意力表现，与较高的静息状态 HRV 有关，这表明 D2 分测验之间的注意力表现可能反映了 HRV 对行为灵活性的促进。
