Symptom and _ symptom of lung source heart disease

Symptom and _ symptom of lung source heart disease
1.There are chronic chest, lung disease history, such as chronic bronchitis, pulmonary emphysema and bronchus asthma, pulmonary tuberculosis, pneumosilicosis,etc., or there is medical history of thoracic deformity and vascular pathological change of the lung.
2.The heart function compensates one and behaves: Mainly send disease, the artery high pressure of lung and loose manifestation of right ventricle originally for the lung, if cough and breathe heavily for a long time, expectoration, palpitation breathes hard, appear and have difficulty in breathing progressively, slight cyanosis, intravenous anger one of neck. The pulmonary emphysema physical sign of both sides: Display the barrel chest, the percussion has presented the voiceless sound, the voiced sound circle of liver has dropped, the heart voiced sound circle shrinks, the respiration is lowered etc.; The position of apex of the heart can see heart systolic phase and beat, the heart rate is accelerated, the second sound of lung artery is hyperfunction, and the systolic phase noise of tricuspid valve district,etc., brief on right ventricular hypertrophy and lung artery high pressure.
3.The heart function loses and compensates one to display two respects:
a. It is depleted to breathe: Have lung that is infected more or sedative usufruct is used improperly as the inducement, display palpitation and breathe hard, have difficulty in breathing, cyanosis, conjunctiva congestion of eyeball edema, have a headache, the head is bloated, the irritation is uneasy, absent-minded, illusion, directional strength obstacle, have a liking for and sleep, the serious one can appear overbearingly and drily, twitch or tremble, even go into a coma, is also called lung encephalopathy.
b. In heart failure: Mainly depleted as the main fact with the right heart. Shown as palpitation breathing hard, cyanosis becomes more serious, intravenous anger one of neck, liver has much tenderness, edema of pair of lower extremities or have ascites, venous pressure increases, little urine, lose the appetite, abdominal distension, it is vomited that disgusting, the heart rate is increased fast, the serious one can present shock and even die.
4.Auxiliary examination:
a. Test the inspection: Hemoglobin and red blood cell often increase, the infeted's neutral cells can increase, the analysis of vim and vigour, blood partial pressure of oxygen and degree of saturation of oxygen of sedan-chair determine, it is normal to be lower than, carbon dioxide it is normal for partial pressure to higher than, can appear blood plasma nonprotein nitrogen and urea nitrogen increase and third valley transfer the intersection of amine and the intersection of enzyme and the intersection of person who increase and liver renal function to, damage, behave.
b. The X-ray examination of chest: Except that pulmonary emphysema behaves, strengthen like the printing opacity of lung, artery branch, especially the artery is done and obviously increased widely under the right lung, greater than 1.5 centimetres, lung arteriectasis, there is detailed and few and peripheral branch, atrium sinistrums, right ventricles are expanded.
c. Electrocardiogram: Display the right of electric axle to lean towards, if the ventricle is loose, lung P wave, bunch props up block and low-voltage cardiac muscle ischemically etc. to change in right.
d. The interesting Fig. of the supersound: Can reveal the right ventricle flows out one to increase widely, right ventricle and lung artery increase, the interventricular septum of heart increases thick, etc.
