本文的目的是研究自发性瞳孔直径波动与心血管变异性信号的自主节律之间的关系。对10名正常受试者同时记录心电图（ECG）、Finapres（一种连续无创血压监测设备）和呼吸数据以及通过便携式红外电视瞳孔计获得的自发性瞳孔直径波动。所有受试者的瞳孔波动功率谱均显示出一个呼吸成分，该成分与心动图和收缩压图的高频成分具有显著的频谱相干性。此外，还识别出低频带中的离散功率分布；在10名受试者中有6名，其与心动图和收缩压图中的低频（LF）功率相干性显著。结论是，在自发性瞳孔直径波动中可以检测到心血管自主节律。
The aim of this paper was to investigate the relationship between spontaneous pupil diameter fluctuations and autonomic rhythms of cardiovascular variability signals. ECG, Finapres and respiration data from 10 normal subjects were recorded simultaneously to spontaneous pupil diameter fluctuations obtained from a portable infrared TV pupillometer. Power spectra of pupillary fluctuations showed in all the subjects a respiratory component with significant spectral coherence with the high frequency components of the tachogram and systogram. Moreover a discrete power distribution in the low frequency band have been identified; coherence with LF power in tachograms and systograms was significant in 6/10 subjects. It is concluded that cardiovascular autonomic rhythms can be detected in spontaneous pupil diameter fluctuations.
