The existing instruments for assessing heart rate (HR) and heart rate variability (HRV) require contact area. This is difficult to obtain from specific groups of patients and from those moving. The aim of this study was to validate the use of the HRVCam software for measuring HR and HRV in healthy adults.
The HR and HRV variables were evaluated in terms of time and frequency using a webcam and Polar S810i. The Shapiro-Wilk test was used to test the normality of the data, and the Pearson's correlation coefficient () was used to identify the possible correlation between the two instruments. The size of the effect was calculated based on a generalized linear model, and the Bland-Altman plots were used to analyse the agreement between the methods. The level of significance for all analyses was set at < 0.05. We evaluated 102 participants, of whom 52% were men; 83.3% were aged between 18 and 29.9 years; and 84.3% were single.
There was a good agreement and moderate to strong correlations among all analysed variables. The biases were low, except for the low frequency/high frequency measures. Moreover, the difference between the samples was small to moderate. The results of this study corroborate the use of HRVCam for measuring HR and HRV.
现有的评估心率（HR）和心率变异性（HRV）的仪器需要接触面积。这对于特定患者群体以及活动中的患者来说很难实现。本研究的目的是验证HRVCam软件在健康成年人中测量HR和HRV的有效性。
使用网络摄像头和Polar S810i从时间和频率方面评估HR和HRV变量。采用夏皮罗-威尔克检验来检验数据的正态性，并使用皮尔逊相关系数（）来确定两种仪器之间可能存在的相关性。基于广义线性模型计算效应大小，并使用布兰德-奥特曼图来分析方法之间的一致性。所有分析的显著性水平设定为<0.05。我们评估了102名参与者，其中52%为男性；83.3%的年龄在18至29.9岁之间；84.3%为单身。
所有分析变量之间存在良好的一致性以及中度至高度的相关性。除低频/高频测量外，偏差较低。此外，样本之间的差异为小到中度。本研究结果证实了HRVCam在测量HR和HRV方面的应用。
