闭塞性肺血管病包括原发性肺动脉高压、肺血栓栓塞和肺静脉闭塞性疾病等,其共同的后果是肺动脉高压和右心室肥厚。为了评价心电向量图对闭塞性肺动脉高压的诊断价值,我们对一组病人的血流动力学进行了比较研究。选择26例肺动脉平均压大于20mmHg和/或收缩压大于30mmHg的肺动脉高压患者,男性10人,女性16人,年龄14—54岁,平均35.5岁。根据病史、体征、X线胸片、心电图、超声心动图、血气分析和右心导管术排除肺实质疾病、分流性心脏病、心脏瓣膜病以及任何原因引起的肺静脉高压。同时排除缺血性心脏病、高血压、室内传导异常及肥厚性心肌病。
Obstructive pulmonary disease including primary pulmonary hypertension, pulmonary thromboembolism and pulmonary venous occlusive disease, the common consequence of pulmonary hypertension and right ventricular hypertrophy. In order to evaluate the diagnostic value of ECG maps for obliterative pulmonary hypertension, we conducted a comparative study of hemodynamics in a group of patients. Sixty-six patients with pulmonary hypertension who had a mean pulmonary artery pressure greater than 20 mmHg and / or a systolic blood pressure greater than 30 mmHg were selected, 10 males and 16 females, aged 14-54 years (average 35.5 years). Pulmonary venous hypertension is excluded based on medical history, signs, X-ray, electrocardiogram, echocardiography, blood gas analysis, and right heart catheterization for pulmonary parenchymal disease, shunt heart disease, valvular heart disease, and any cause. At the same time rule out ischemic heart disease, hypertension, abnormal conduction and hypertrophic cardiomyopathy.
