小儿高原性心脏病与房间隔缺损的鉴别诊断研究

THE STUDY ON DIFFERENTIATING DIAGNOSIS OF ATRIAL SEPTAL DEFECT OR HIGH ALTITUDE DISEASE AT HIGH ALTITAUDE AREA OF CHILDREN

高原地区小儿房间隔缺损（ASD）发病率高，临床表现与高原性心脏病（HAHD）相似，本文对36例ASD与32例HAHD患儿的体征，ECG，2DUCG，PWD血流显像，X光胸片共20项指标进行分析发现，极有鉴别意义的指标为P2固定分裂，右下肺动脉宽度，肺动脉峰值流速，肺静脉血流频谱形态和峰值流速。

The incidence of ASD was high and its physical sign was similar with HAHD specially in children at high altitude. By contract the 20 parameters of physical sign such as ECG, chest X-Ray, 2D-UCG, PWD,CDFI between 36 cases of ASD and 32 cases of HAHD in children patients. Result was that the very significant parameters of differentiating dignosis on ASD or HAHD were found: P2 fixed split. the width of right lower pulmonary artery, the diameter of right atrial, RVAW,PA, VP, AT, VP of ASD. Profile and VP of PVF by Dopplerechocardiogram.
