心率变异性（HRV）通常用于分析创伤后应激障碍（PTSD）患者的压力、焦虑和抑郁。心率可以使用欧拉视频放大（EVM）方法使用皮肤中的微运动来可视化。HRV可用于帮助与PTSD相关的惊吓反应的人。本文探讨了如何使用一种专为治疗PTSD患者的治疗师和社会工作者设计的工具从视频中捕获心率。我们对使用健身监测器测量的已知心率的受试者测试了该工具。此外，该工具还针对YouTube上个人谈论他们患PTSD的经历的视频进行了测试。结果表明，该工具能够描述YouTube视频中个人心率变异性的降低。然而，在我们的准确性研究中，该工具无法处理肤色较深的人的视频。
Heart rate variability (HRV) is commonly used to analyze stress, anxiety, and depression in persons suffering from post-traumatic stress disorder (PTSD). Heart rate can be visualized using micro-movements in the skin using the Euler video magnification (EVM) method. HRV may be used to help persons with startle reactions associated with PTSD. This paper examines how heart rate can be captured from video using a tool designed for use by therapists and social workers that treat PTSD sufferers. We tested the tool against subjects with known heart rates taken using a fitness monitor. Also, the tool was tested against YouTube videos of individuals talking about their experiences with PTSD. Results showed that the tool was able to depict decreases in heart rate variability for individuals in the YouTube videos. However, the tool could not process videos with darker skinned individuals in our accuracy study.
