肺微分血流图的 C 波上升支与基线交点 B 和下降支的最低点 Y 定位目前还存在不同的看法,为了探讨此问题对141名健康人及81例肺心病患者共222例进行研究。141名正常人男性88例,女性53例,在微分图上均有交点 B。其中44名(31%)除有交点 B 外,在上升支也有拐点 B′。肺心病组81例男性53例,女性28例,均有交点 B,其中33例(14%)也有拐点 B′。所以正常人或肺心病患者在微分图上均有明确的交点 B,有拐点者仅
There are still different opinions about the rise of C wave in pulmonary differential blood flow map from the baseline intersection point B and the lowest point of descending branch Y. A total of 222 healthy subjects and 81 pulmonary heart disease patients were studied in this study. There were 88 cases of 141 normal men and 53 cases of women, all of which had intersection point B on the differential graph. Of these, 44 (31%) had an inflection point B ’on the ascending branch, with the exception of point B. In the pulmonary heart disease group, there were 53 males and 28 females with 81 intersections, of which 33 (14%) also had inflection point B ’. So normal or pulmonary heart disease patients in the differential graph have a clear intersection point B, inflection point only
