Clinical applications of passive long-term heart rate (HR) monitoring in patients with cardiac arrhythmias include adequate drug titration of atrioventricular (AV) nodal drugs and assessment of medical compliance with treatment. A majority of patients treated with beta-blockers, especially patients with atrial fibrillation (AF), require some degree of drug titration during the first 6 months of treatment to ensure that adequate HR control and medicine compliance has been achieved. Failing to achieve adequate rate control in patients with AF can lead to worsening symptoms, heart failure exacerbations, and potentially tachycardia-induced cardiomyopathy. Enabling video-based monitoring during telehealth patient visits could facilitate providers to measure heart rate (HR) without the need for a dedicated home device (smartwatch, SPO2 device, or others). Videoplethysmography (VPG) is a monitoring technology that measures pulse rate by utilizing front-facing cameras embedded in smart devices. VPG provides a remote and contactless cardiac monitoring solution. We conducted a clinical experiment to evaluate the accuracy of VPG in measuring HR while running on two portable devices: Samsung S10 smartphones and S3 tablets. We used a single‑lead ECG to measure the heart rate at the time of the VPG recordings in AF patients. We employed the Bland-Altman method to measure the level of agreement between videoplethysmography and ECG-based measurements of HR. The findings reveal that the mean difference in videoplethysmography and ECG-based heart rate was inferior to 1 bpm across the 2 devices with confidence intervals ranging from 3 to 12 BPM. Our facial video-based HR monitoring solution could assist providers in measuring heart rates in their patients with AF during remote telehealth visits.
被动长期心率（HR）监测在心律失常患者中的临床应用包括房室（AV）结药物的充分药物滴定和评估治疗的医疗依从性。大多数接受β受体阻滞剂治疗的患者，特别是患有心房颤动（AF）的患者，在治疗的头 6 个月内需要进行一定程度的药物滴定，以确保达到适当的 HR 控制和药物依从性。未能在 AF 患者中实现充分的心率控制可导致症状恶化、心力衰竭恶化，并可能导致心动过速性心肌病。在远程医疗患者就诊期间启用基于视频的监测，可以使提供者无需专用家庭设备（智能手表、SPO2 设备或其他设备）即可测量心率（HR）。视频体积描记法（VPG）是一种通过利用智能设备中嵌入的前置摄像头来测量脉搏率的监测技术。VPG 提供了一种远程、非接触式的心脏监测解决方案。我们进行了一项临床实验，以评估 VPG 在运行于两种便携式设备（三星 S10 智能手机和 S3 平板电脑）时测量 HR 的准确性。我们使用单导联心电图在 AF 患者的 VPG 记录时测量心率。我们采用 Bland-Altman 方法测量 VPG 和基于 ECG 的 HR 测量之间的一致性水平。结果表明，两种设备的 VPG 和基于 ECG 的心率的平均差异均低于 1 bpm，置信区间为 3 至 12 bpm。我们的基于面部视频的 HR 监测解决方案可以帮助提供者在远程远程医疗访问期间测量 AF 患者的心率。
