Photoplethysmography has been used simultaneously with ambulatory venous pressure measurements to study 32 patients. Of the 62 limbs studied, 24 were normal, 20 had primary varicose veins, and 18 had deep valvular incompetence. The results indicate that the photoplethysmographic refilling time can provide a good separation between the three groups when the test is performed in the standing, but not in the sitting, position. However, the test is qualitative because we found a lack of correlation between the short refilling times in limbs with deep venous insufficiency and the ambulatory venous pressure.
已将光电容积描记法与动态静脉压测量同时用于研究32例患者。在所研究的62条肢体中,24条正常,20条有原发性静脉曲张,18条有深静脉瓣膜功能不全。结果表明,当在站立位而非坐位进行测试时,光电容积描记法的再充盈时间能够很好地区分这三组。然而,该测试是定性的,因为我们发现有深静脉功能不全的肢体中较短的再充盈时间与动态静脉压之间缺乏相关性。
