我们开发了一种带有加速度传感器的手表式心率（HR）记录仪（WT-HR转速计），可以长时间（> 120 h）逐分钟记录HR和身体活动（ACT）。为了研究其应用，我们将这些测量结果与24小时血压（BP）和心率变异性、交感迷走神经平衡和静息能量消耗（REE）进行了比较。WT-HR转速计采用Seiko蓝色传感器测量手腕处的HR，并采用加速度传感器每4秒测量一次身体ACT。采用WT-HR心率仪对50名健康大学生进行了24 h的HR和ACT测定。然后计算清醒时的最小HR和平均HR，并推导出ΔHR。在同一天，24小时BP和LF/HF（低频成分/高频成分的ECG-RR间期功率谱）测量与多生物医学记录仪，REE测量与便携式热量计。与Holter-ECG相比，WT-HR转速计可准确测量HR。ΔHR与ΔSBP之间存在显著相关性。ΔHR与ΔLF/HF（清醒时间=无身体运动的清醒时间）之间也有显著相关性，HR与REE之间也有显著相关性。这些结果表明ACT和ΔHR可用于评估日常生活中的精神和体力活动。WH-HR转速计将用于评估日常生活中的精神和身体活动。
We have developed a wristwatch-type heart rate (HR) recorder (WT-HR tachometer) with an acceleration-pickup sensor, which can record HR and body activity (ACT) minute by minute for a long time (> 120 h). To study its application, we compared these measurements with 24-h blood pressure (BP) and HR variability, sympathovagal balance, and resting energy expenditure (REE). The WT-HR tachometer incorporates a Seiko-blue sensor to measure HR at the wrist and an acceleration-pickup sensor to measure body ACT every 4 sec. Fifty healthy university students underwent measurement of HR and ACT by the WT-HR tachometer for 24 h. Then we calculated the minimum HR and mean HR during waking time and derived ΔHR. On the same day, 24-hr BP and LF/HF (low frequency component/high frequency component of ECG-RR interval power spectrum) were measured with a multibiomedical recorder, and REE was measured with a portable calorimeter. The WT-HR tachometer accurately measured HR, compared with the measurements by Holter-ECG. There was a significant correlation between ΔHR and ΔSBP. There also was a significant correlation between ΔHR and ΔLF/HF, (waking time = waking time without body movement) and a significant correlation between HR and REE. These results suggest that ACT and ΔHR are useful for evaluating mental and physical activity of daily life. The WH-HR tachometer will be useful for assessment of mental and physical activity in daily life.
