本文报告先天性心脏病26例右心导管及超声多普勒的检查结果、发现肺动脉高压患者,多普勒肺动脉血流频谱的特点为:RPEP 延长,TPV 缩短,频移增大,频谱宽度相对变窄.当肺动脉压力超过30mmHg 时,RPEP>0.09秒者占81%,TPV<0.13秒者占90%。至于肺动脉高压程度与各参数绝对值之间的关系,还需积累更多资料方能进一步阐明。判断其意义时,尚应注意结合他其临床资料和影响因素综合分析。
This paper reports 26 cases of congenital heart disease right heart catheterization and ultrasound Doppler examination results found that pulmonary hypertension patients, Doppler pulmonary artery blood flow spectrum features: RPEP extension, TPV shortening, frequency shift increases, the relative width of the spectrum Narrowed.When the pulmonary artery pressure exceeds 30mmHg, RPEP> 0.09 seconds accounted for 81%, TPV <0.13 seconds accounted for 90%. As for the relationship between the degree of pulmonary hypertension and the absolute value of each parameter, the need to accumulate more information to further clarify. Judgment of its significance, should pay attention to his clinical data and comprehensive analysis of factors.
