Check _'s symptom in narrow diagnosis of lung artery one
1,The new works are normal in size when X-ray examination is light and intermediate and narrow, the severe narrow heart if the sound function is in line, heart increase slightly only, decline intentionally and heart increase obviously, expand for right room and right room mainly. The lung after being narrow is bought and expanded for the change of characteristic this disease, expand to extend to the left lung artery but not expand more obvious of in infancy sometimes. 2,The electrocardiogram electrocardiogram will reveal the left room will be expanded, P wave is towering. The electrocardiogram can also reveal the right of loose electric axle of left room leans towards, its intensity depends on the narrow severity. The right chest leads the way and unites revealing P wave is towering, narrow and serious lung arteriectasis is a change of characteristic this disease, expand sometimes and extend to the left lung artery but not expand more obvious of in infancy. 3,Supersound aroused in interest to pursue, can reveal the intersection of lung and the intersection of artery and thickness of one while being aroused in interest to pursue by two-dimentional supersound, the beginning situation while shrinking and expansion after being narrow, can check the atrium level to shunt while paving supersound more, the more important thing is that can estimate and examine a narrow severity of lung artery more reliably. 4,The heart conduit checks the pressure of right ventricle and obviously increases, can be equal to pressure of systemic circulation, and lung the intersection of artery and pressure reduce obviously, whom continuous curve reveal obviously when heart conduit withdraw from lung artery to ventricle it has pressures of transition region to be poor in steps. 5,Radiography of cardiovascular vessel The radiography of right ventricle can be seen the obvious one " Solicit the efflux " At the same time can reveal lung artery petals of leaf increase thick or or development bad to enter the intersection of lung and whom artery do always, expand after being narrow.
