目的：本研究的目的是通过心率变异性（HRV）的频谱分析来评估仰卧位、左侧卧位和右侧卧位对老年人自主神经活动的影响。方法：45例成人，年龄73.6 ± 5.7岁。所有受试者仰卧位后随机移至侧卧位并保持10 min，同时记录心电图数据以测量心率变异性。结果如下：与其他两种体位相比，当参与者处于左侧卧位时，最低心率持续10分钟（p <0.001），而HRV指标保持不变。右侧卧位的低频与高频HRV比值（LF/HF）显著低于其他体位。讨论：右侧卧位可能减弱老年人的交感神经活动。
Objectives: The aim of this study was to evaluate the effect of the supine, left lateral decubitus, and right lateral decubitus positions on autonomic nervous activity in elderly adults by using spectral analysis of heart rate variability (HRV). Method: Forty-five adults aged 73.6 ± 5.7 years were enrolled. After lying in the supine position, all participants moved to the lateral decubitus positions in a random order and maintained the positions for 10 min, while electrocardiographic data were recorded to measure HRV. Results: The lowest heart rate continued for 10 min when participants were in the left lateral decubitus position compared with the other two positions (p < .001), while the HRV indexes remained unchanged. The low-frequency HRV to high-frequency HRV ratio (LF/HF) for the right lateral decubitus position was significantly lower than that for the other positions. Discussion: The right lateral decubitus position may attenuate sympathetic nerve activity in elderly adults.
