摘要

7名健康受试者(6岁，11岁，平均年龄23岁)在上午9点至下午6点每隔3小时静息时桡动脉脉搏压波(PPWs)。ppw的变化分析包括波浪间差异的平方和、方差分析和波浪成分的谱分析。上午9点记录的ppw与下午6点记录的ppw无显著差异，但其他时间段之间的ppw差异显著，上午9点和下午3点之间差异最大。ppw的频率成分也有一定的变化，随着时间的推移，高频成分增加。这项研究的发现支持了中医的建议，即PPW全天都在变化。

Analysis of the diurnal variation of arterial pressure waves

Pulse pressure waves (PPWs) were recorded from the radial artery using photoplethysmography in 7 healthy subjects (6M, 1F, mean age 23 yrs) at rest every 3 hours between 9 am and 6 pm. Analysis of variations of PPWs included sum of square differences between waves, ANOVA and spectral analysis of the components of waves. PPWs recorded at 9am were not significantly different to PPWs recorded at 6 pm, however, PPWs between each other time period were significantly different, with the largest difference occurring between 9 am and 3pm. There was also some variation in the frequency components of the PPWs with an increase in higher frequency components as the day progresses. The finding of this study supports the suggestion within TCM that there are changes in PPW throughout the day.
