What is the physical sign of the plump type myocardium disease? 's general knowledge
Plump type myocardium disease is plump with the skin of ventricle. The model person regards interventricular septum as it very in the left ventricle, even and can present a concentric a plump a kind of myocardium disease that is the characteristic. A of volume of left ventricle is normal or reduces. Even and pathological change takes place in the right ventricle. It is usually the dominant heredity of autosome.
Common physical sign
The systolic phase of apex of the heart department beats; Because the cardiac muscle is plump, it is obvious that beats to strengthen. Because the left ventricle is reduced, the atrium shrinks and strengthens, the blood flow strikes the left ventricular wall, excited before there can be systolic phase in the apex of the heart department. Last the second systolic phase to beat after the first sound, form systolic phase and beat doubly.
Systolic phase is thin to tremble; In the apex of the heart department more. There are thin persons who tremble of systolic phase, it is more relatively heavy that left ventricle flows out one and obstructs.
Systolic phase noise; Present on the brestbone left bottom flange or inside of apex of the heart " The coarse drying " The noise in later period, is caused by the fact that the left ventricle flows out one to obstruct while shrinking. The factor strengthening myocardium contractile force or reducing artery resistance, can make the pressure difference between left ventricle and aorta increase, the noise is strengthened, the factor can reduce myocardium contractile force or increase artery resistance ing, can make the pressure steps reduce badly, the noise is weakened. When the energies of going back amount increase, the noise is weakened. Energies of answering quantity reduces the noise to strengthen.
Systolic phase noise of apex of the heart department; About 50% of this disease can not be closed completely with the bicuspid valve, therefore the apex of the heart department has later period noises while shrinking, or the whole systolic phase noise.
Third heart sound and fourth sound.
