肺血流图能反映心动周期中血管转动性容量变化,可间接了解心脏排血规律,肺循环压力增高情况及肺血管弹性减退的程度。为了提高肺心病的诊断率和动态观察肺心病肺循环的改变,我们对65例肺心病急性期患者进行了肺血流图检查,并与40岁以上正常人肺血流图的各项参数进行 Pulmonary blood flow map can reflect changes in the capacity of blood vessels in the cardiac cycle, can indirectly understand the law of cardiac blood flow, increased pulmonary pressure and pulmonary vascular elasticity of the degree of decline. In order to improve the diagnostic rate of pulmonary heart disease and dynamic observation of pulmonary heart disease changes in pulmonary heart disease, 65 cases of pulmonary heart disease in patients with acute pulmonary hemorrhage examination, and more than 40 years of age with pulmonary blood flow diagram of the various parameters
