目的：本研究调查了通过指尖光电体积描记法 (PPG) 和使用心频率计 (Polar RS800cx) 对肥胖青少年进行短期静息心率变异性 (HRV) 评估的准确性和可靠性。青少年肥胖可能与胰岛素抵抗和/或中央脂肪增加导致的自主神经功能障碍有关。这一事实可能会影响静息自主活动评估的准确性和可靠性。方法：14 名被归类为肥胖且表现出胰岛素抵抗的青少年（15 +/- 2 岁）接受了以下程序：(a) 人体测量，以及 (b) 使用 ECG、PPG 和 Polar RS800cx 同时进行两次 25 分钟仰卧位 HRV 记录。结果：结果显示，使用 Polar RS800cx 和 PPG 获得的 HRV 标记与通过 ECG 获得的 HRV 标记之间存在显着相关性，决定系数 (R-2) 和组内相关系数分别为 0.60 至 0.98（P 值范围为 0.03 至 0.05）和 0.70 至 0.99（P 值范围为 0.01 至 0.05）。 ECG 的测量技术误差和重测可靠性的组内相关系数分别为 8.9% 至 45.8% 和 0.38 至 0.68，Polar RS800cx 的测量技术误差为 8.0% 至 30.5%，组内相关系数为 0.29% 至 0.61，PPG 的测量技术误差为 7.2% 至 54.6%，组内相关系数为 0.45% 至 0.64。结论：在评估肥胖青少年静息心率的自主控制时，Polar RS800cx 和 PPG 计算的 HRV 指数似乎与 ECG 数据一样准确且可重复。
Aim: This study investigated the accuracy and reliability of short-term resting heart rate variability (HRV) assessment by fingertip photoplethysmography (PPG) and using a cardiofrequencimeter (Polar RS800cx) in obese adolescents. Obesity in adolescents may be related to autonomic dysfunction due to insulin resistance and/or increased central fat. This fact may affect the accuracy and reliability of the evaluation of autonomic activity at rest. Methods: Fourteen adolescents (15 +/- 2 years) classified as obese and exhibiting insulin resistance underwent the following procedures: (a) anthropometric measurements, and (b) two 25-min HRV recordings in a supine position conducted simultaneously using ECG, PPG, and Polar RS800cx. Results: The results showed significant correlations between HRV markers obtained using Polar RS800cx and PPG and those obtained from ECG, with coefficients of determination (R-2) and intraclass correlation coefficients ranging from 0.60 to 0.98 (P-value ranging from 0.03 to 0.05) and 0.70 to 0.99 (P-value ranging from 0.01 to 0.05), respectively. The technical error of measurement and intraclass correlation coefficients for test-retest reliability ranged from 8.9 to 45.8% and 0.38 to 0.68 for ECG, 8.0 to 30.5% and 0.29 to 0.61 for Polar RS800cx, and 7.2 to 54.6% and 0.45 to 0.64 for PPG, respectively. Conclusion: HRV indices calculated by Polar RS800cx and PPG appear to be as accurate and reproducible as data from ECG when evaluating the autonomic control of heart rate at rest in obese adolescents.
