The lung artery one can not close completely symptom and _'s symptom of physical sign
The clinic that most cases have illness coming on originally does very well, the lung artery one closes manifestation not complete and is concealed, only find on auscultation once in a while. Physical sign is as follows: First, laying one's hand on among blood vessel and the second rib of left reason of heartbeat brestbone and lung artery systolic phase beat, can accompany and shrink or relaxation one is vibrated. Lay one's hand on by the intersection of brestbone and left bottom flange and right ventricle high power systolic phase beats. Second, the intersection of heart sound and the intersection of lung and artery, at the high pressure, second sound the intersection of lung and the intersection of artery and a composition strengthen. The heart undulate quantity of right ventricle increases, penetrates the time of blood to lengthen, the second sound is presented widely and split. The right heartbeat amount increases to make the lung artery already expanded expand and produce systolic phase to spray the sound suddenly, the most obvious among the second rib of left reason of brestbone. Often have third and fourth sound among the 4th rib of left reason of brestbone, strengthen while inhaling. Third, heart murmur continue take place on the intersection of lung and the intersection of artery and high pressure person, relaxation that begin immediately sigh kinds of the intersection of lofty tone and decreasing type noise early period have second sound among the intersection of brestbone and left the intersection of reason and 2- 4 rib, strengthen while inhaling, is called Graham Steell noise. Tion of reason and the second rib, have the intersection of systolic phase and the intersection of injection nature and noise spray sound, among the intersection of brestbone and left the intersection of reason and the second rib.
