肺动脉高压是指肺平均压((?)ap)在静息时高于20mmHg 或运运动时高于30mmHg。在静息时已高于正常称为显性肺动脉高压;如在静息时 Pap尚正常,仅当运动时超过30mmHg,称为隐性肺动脉高压。肺动脉高压为临床常见的病理过程。过高的肺 Pulmonary hypertension refers to the mean lung pressure ((?) Ap) above 20 mm Hg at rest or above 30 mm Hg during exercise. At rest has been higher than the normal known as dominant pulmonary hypertension; such as Pap is still normal at rest, exercise only when more than 30mmHg, called recessive pulmonary hypertension. Pulmonary hypertension is a common clinical pathological process. Excessive lungs
