Diagnosis _'s symptom of lung source heart disease

Diagnosis _'s symptom of lung source heart disease
Check
First, X-ray examination, besides lung, chest basic disease and characteristic that the acute lung infects, Shang Ke has lung arteries to solicit under high pressure, the pulmonary trunk is expanded such as right, it is greater than or equal to 15mm directly that it is horizontal; The ratios of its horizontal foot-paths and horizontal foot-paths of trachea are greater than or equal to 1.07; The lung artery section obviously stresses or its height is greater than or equal to 3mm; Solicit right ventricular hypertrophy, it is all a main basis of diagnosing lung worry. Specific patient in heart failure to can see shadow dwindle to some extent outside the heart control.
Second, the intersection of heart and electricity enclose, check, display have right change of ventricular hypertrophy mainly, such as electric the intersection of axle and Right deviation being partial, average electric axle greater than or equal to +90o is severe along clock to turn location, Rvl +Sr5 greater than or equal to 1.05mV and lung type P wave the volume. Also can be seen the right bunch and prop up block and low-voltage figure, can be regarded as the reference condition of diagnosing lung worry. Prolong in V1, V2 even to V3, can present QS wave which is exactly like the outmoded myocardium infarction figure, should pay attention to distinguishing. Typical lung worry.
Third, the intersection of heart and electric vector quantity enclose, check, show as atrium dextrum, right figure of ventricular hypertrophy mainly. Aggravated with the intensity of the right ventricular hypertrophy, QRS position or and then developed into right gradually, turned downwards, finally to right from the normal left, but the department of ending is still after right. It surround QRS since against clock in operation or " 8" Along clock to run whom shape develop to when being severe. How narrow P ring is, P surrounds the amplitude to increase left side and forehead, the maximum vector quantity makes forward, Left deviation or right. Generally speaking, it is obvious that the atrium dextrum is loose, then P surrounds the vector quantity right.
Fourth, supersound aroused in interest to enclose, check through determine right ventricle flow out an internal diameter ' Greater than or equal to 30mm) ,Right ventricle internal diameter ( Greater than or equal to 20mm) ,The thickness of the wall before the right ventricle, the ratios of Left deviation, right ventricle internal diameter ( lt; 2),The right lung artery internal diameter presents qR, V5R/ Slt; 1,Rv1+Sv5 =1: Such indexes as 5mV or pulmonary trunk and atrium dextrum are loose, in order to diagnose lung worry.
Fifth, the intersection of lung and the intersection of impedance and the intersection of blood flow and picture and their differential pursue, check domestic research, prove lung the intersection of lung and the intersection of impedance and amplitude and differential wave value that blood flow pursues reduce more at the worry, Q-B (equivalent to that the right room penetrates in blood earlier stage) Time is lengthened, B-Y (quite right room penetrates the blood one) Time is shortened, Q-B/ B-Y ratio increases, consults meanings, and there is obvious relevance on predicting lung arterial pressure and sport, there is certain reference value.
Sixth, analysis lung worry lung function of vim and vigour of the artery compensate one and can present hypoxemia disease or amalgamate high carbonic acid blood disease, as one, acute aggravates one to control and infect actively; Unobstructed respiratory tract, improve the breathing function; Correct oxygen deficiency Paco2lt; 60mmH, PaC02gt; 50mmHg shows yes breathes depletedly.
Seventh, blood can rise while checking erythrocyte and hemoglobin. Viscosity and blood plasma viscosity of whole blood can increase, the electric swimming time of erythrocyte is often lengthened; While amalgamating and infecting, the total number of leucocytes increases, neutral cells increase. Some patient serology can have renal function or liver function to change while checking; Serum potassium, sodium, chlorine, calcium, magnesium can change. Besides potassium, the others are normal more.
Eighth, other the intersection of lung and function check to early relieving issues of the intersection of lung and worry patient meaningful. Phlegm bacteriology check to can guide the exertion against fungus medicine while being acute to aggravate a lung worry.
Diagnosis
Revise in our country according to 1977 " The worry diagnostic standard of chronic lung " ,The patient has slow propping up, pulmonary emphysema, other lung chest diseases or vascular pathological changes of the lung, therefore cause artery high pressure of lung, right ventricular hypertrophy or right heart function not to behave completely, and above-mentioned electrocardiogram, X-ray behave, and then consult the electricity of heart to scalogram, ultrasonic heart cardon, lung impedance blood flow picture, lung function or other inspections, can make diagnosis.
