Analysis on Parameters of Photoplethysmogram of Commonly - seen Pulse Conditions at the Cun -kou Area / 中医杂志

ABSTRACT

To study the relationship between the different pulse conditions and photoplethymograms, the photoplethysmogram of 432 subjects, including normal pulse condition and 10 commonly - seen abnormal pulse, was examined at Cun - kou area with a BC - 4 quantitative photoplethysmograph. Meanwhile hemodynamic parameters were analysed. As compared with the normal pulse, photoplethysmograms of different pathological pulse conditions at Cun - kou area showed their specifical parameters and the changes of hemodynamic parameters reflected features of cardiovascular pathophysiology formed by different pulse conditions. It suggests that photoplethysmograms at the Cun -kou area can supply objective basis for clinical diagnosis of different pulse conditions.
