The lung artery one can not close completely the disease and sum up _'s general knowledge
For continue, take place on the intersection of lung and the intersection of artery and high pressure root of pulmonary trunk expanding, causing a ring to expand most common cause of disease, such as rheumatism bicuspid valve damage, ending to catch graceful dose of syndrome etc.; Lung arteriectasis of all syndrome for specially sending or horse that I haven't seen you for a long time. It does not cause the capacity overrexertion of right room completely that the lung artery one is closed, if there is no artery high pressure of lung, can have tolerated for many years; If there is artery high pressure of lung, accelerate the right room depletedly and happen. Clinical manifestation: And extended lung artery systolic phase beats, can accompany and shrink sometimes or relaxation one is vibrated. Lay one's hand on by the intersection of brestbone and left bottom flange and right the intersection of room and high power systolic phase beats. Second, heart sound lung artery high pressure person, a composition of lung artery of second sound strengthens. The second sound is presented widely and split. The right heartbeat amount increases and causes the lung artery already expanded to expand and produce systolic phase to spray the sound suddenly, the most obvious on the intervals of rib the second of left reason of brestbone. The 4th rib interval of left reason of brestbone often has right room third and fourth sound, strengthen while inhaling. Third, heart murmur . Regard treating the primary disease which causes the artery high pressure of lung as the main fact, obstruct as relieving mitral stenosis. Only when serious lung artery one is returned to to flow to cause the obstinate right room to be depleted, the beginning carries on the surgery treatment to this valve.
