The most important pathomorphological hallmarks of cor pulmonale are:

Answer]: c Cor pulmonale disease develops from chronic extensive lung and thoracic diseases, and respiratory and circulatory symptoms are often mixed. It is generally believed that patients with chronic extensive pulmonary and thoracic diseases can be diagnosed by the Chiropractic Department once pulmonary hypertension and right ventricular enlargement are found to have the possibility of clefted heart satura hidden organ disease that causes right heart enlargement.

Briefly describe the key points of diagnosis of cor pulmonale.

A:(1) Have a history of severe COPD, other thoracic and pulmonary diseases, or pulmonary vascular disease.

2) Signs of pulmonary hypertension, right ventricular hypertrophy or right heart insufficiency, such as P2>A2, jugular venous distention, hepatic tenderness, positive hepato-jugular venous reflux sign, lower limb edema, etc.

3) Electrocardiogram, chest X-ray, echocardio** and other examinations show signs of pulmonary hypertension and right ventricular hypertrophy.

4) Exclude other diseases with similar manifestations, such as congenital heart disease, coronary heart pain, etc.

After the reform of the self-study examination, there are only two exams left in a year, and I want to shout at Hu to seize the opportunity and strive to graduate as soon as possible.

Thanks to the teacher of the school's "English (II)", English is very difficult for me, but after signing up for the class, I followed the teacher's progress in Sun Chen's class to learn, I feel different, I seem to be able to understand, thank you very much for this platform.

The most basic pathological change in the shock lung is ().

a.Pulmonary edema.

b.Alveolar microatrophy.

c.Alveolar cavity membrane formation.

d.Alveolar-wool socks infiltrate the capillary membrane injury.

e.Alveolar wall microvascular thrombosis.

The correct answer is yes: d

Analysis: The main symptoms of cor pulmonale are long-term recurrent cough and sputum production. In the cold season, the cough worsens, and the sputum increases, thickens or turns yellow.

Symptoms such as shortness of breath, shortness of breath, palpitations, pain in the precordial area, fatigue, and chest tightness may improve after resting when you move up stairs or walk briskly. The fingertips, lips and around the lips are bluish-purple. Increased heart rate and irregular heartbeat.

Guidance: It is generally believed that patients with chronic extensive pulmonary and thoracic diseases can be diagnosed with pulmonary arterial hypertension and right ventricular enlargement once they are found to have pulmonary hypertension and other heart diseases that cause right ventricular enlargement are excluded.

If the veins are distended, hepatic venous return (+) hepatic tenderness (+) edema of the lower extremities. The right lower pulmonary artery is dilated, with a ratio greater than the bronchi and a transverse diameter greater than 15 mm. And the pulmonary artery trunk is dilated, and the surrounding bronchioles are slender, and stubs can be seen.

b.Ultrasonography shows that the right ventricular outflow tract is greater than 30 mm, the right ventricular diameter is greater than 20 mm, and the ratio of left and right ventricles is less than 2. ECG may show right axis deviation and atrioventricular block, and right bundle branch block and hypovoltage manifestations suggest cor pulmonale.

a.Wider and shorter.

b.There are two fissures.

c.There is a heart-to-heart notch.

d.The leading edge is straight.

e.It is divided into three leaves.

Correct number of respondents in the first sock of the case: c
