经多普勒超声检测２０例先天性心脏病（ＣＨＤ）患儿三尖瓣最大返流速度来估测肺动脉收缩压（ＰＡＳＰ），旨在探讨该法的准确性及临床意义。２０例ＣＨＤ患儿均伴肺动脉高压（ＰＨ）和三尖瓣返流（ＴＲ），男女各１０例，年龄３～１４岁，平均（６．８±３．５）岁。其中室间?
Pulmonary arterial systolic pressure (PASP) was estimated by Doppler echocardiography in 20 children with congenital heart disease (CHD) to investigate the accuracy and clinical significance of this method. Twenty patients with CHD were accompanied by pulmonary hypertension (PH) and tricuspid regurgitation (TR). There were 10 males and 10 females, aged from 3 to 14 years (mean, 6.8 ± 3.5) years. Which room?
