Background Photoplethysmography (PPG) sensors, typically found in wrist-worn devices, can continuously monitor heart rate (HR) in large populations in real-world settings. Resting heart rate (RHR) is an important biomarker of morbidities and mortality, but no universally accepted definition nor measurement criteria exist. In this study, we provide a working definition of RHR and describe a method for accurate measurement of this biomarker, recorded using PPG derived from wristband measurement across a 24 hour cycle.

逐个测量：24 小时周期内的静息心率

背景光电容积脉搏波 (PPG) 传感器通常在腕戴设备中找到，可以在现实环境中持续监测大量人群的心率 (HR)。静息心率 (RHR) 是发病率和死亡率的重要生物标志物，但尚无普遍接受的定义或测量标准。在这项研究中，我们提供了 RHR 的工作定义，并描述了一种准确测量该生物标志物的方法，使用从 24 小时周期的腕带测量得出的 PPG 进行记录。
