应用脉冲式或连续式多普勤超声技术，对１８例海拔３２００ｍ高原正常人及２５例高原性心脏病（ＨＡＨＤ）患者测定其肺动脉压。正常组及ＨＡＨＤ无瓣膜返流组１０例（４０％）应用Ｈａｈａｍ回归方程，ＰＡＭＰ分别为２．８４±０．４及３．７３±０．５７（ｌｋＰａ＝７．５ｍｍＨｇ）；ＨＡＨＤ有三尖瓣返流组８例（３２％）用ＴＲＰＧ法测得ＰＡＳＰ为６．１３±１．７３ｋＰａ；ＨＡＨＤ有肺动脉瓣返流组７例（２８％）用ＰＲＰＧ法测得ＰＡＤＰ为４．０±０．７３ｋＰａ。表明多普勒超声技术的不同方法可用于不同病理状态上高原低氧性肺动脉高压的测定，并揭示了出现瓣膜返流改变时高原低氧性肺动脉高压的程度。
Pulmonary arterial pressure was measured in 18 patients with elevation of 3200 m and 25 patients with high altitude heart disease (HAHD) by pulsed or continuous doppler ultrasound. Haham regression equation was used in 10 cases (40%) of the normal group and HAHD valveless regurgitation group, PAMP was 2.84 ± 0.4 and 3.73 ± 0.57 (lkPa = 7.5mmHg) respectively; HAHD had tricuspid valve PASP was 6.13 ± 1.73 kPa in 8 cases (32%) in the regurgitation group and 7 cases (4.0%) in 7 cases (28%) in the HAHD group with pulmonary valve regurgitation. 73kPa. Show that different methods of Doppler ultrasound technology can be used for the determination of hypoxic pulmonary hypertension in different pathological conditions and reveal the degree of hypoxic pulmonary hypertension in the presence of valvular regurgitation.
