Condition analysis:
Hypertrophic cardiomyopathy (a) X-ray examination: normal or increased heart size, heart size and heart and left ventricular outflow tract pressure gradient between the proportional, the greater the pressure gradient, the greater the heart. The left ventricle hypertrophy based, not widened aorta, pulmonary artery segment no more prominent, mostly mild pulmonary congestion, common mitral valve calcification.
(B) ECG: Because cardiac ischemia, repolarization abnormalities, ST-T changes in common, left ventricular hypertrophy and left bundle branch block also were more common, probably due to ventricular septal hypertrophy and the emergence of Q wave myocardial fibrosis, various types of the disease is also often arrhythmia.
(C) echocardiography: is an important non-invasive diagnostic methods. Mainly there abnormal thickening of the interventricular septum, interventricular septum diastolic thick 15mm. septal decreased range of motion, generally 5mm. interventricular septum thickness / left ventricular posterior wall thickness ratio of up to 1.5-2.5:1, is generally believed that the ratio 1.5:1 has diagnostic significance. left ventricular end systolic diameter smaller than normal. contraction compartment and the second starting time the distance between mitral anterior leaflet often significantly reduced. mitral systolic forward movement, close to the interventricular septum, before the end of the second heart sound. aorta mid o


ff. more than seven should be a comprehensive analysis, can only come correct conclusion should be noted that hypertension, hypothyroidism, can cause a similar performance.
(D) Cardiac Catheterization and Cardiovascular Imaging: Cardiac catheterization, left ventricular and left ventricular outflow tract pressure gradient between the left ventricular end-diastolic pressure increased, the pressure gradient and left ventricular outflow tract obstruction was positively correlated. Heart angiography, ventricular septal muscle hypertrophy is significant, visible ventricular cavity was narrow crack-like changes in the diagnosis of sense.
Suggestion:
Dilated cardiomyopathy: X-ray examination showed the heart shadow expansion, late appearance, such as spherical, indicating that the cardiac chambers was greater shape resembling pericardial effusion. A small number of patients to the left ventricle, left atrium or right ventricle increases mainly the appearance of similar to the mitral valve. fluoroscopy see weaker than normal heart beat. aortic generally do not expand. course of the disease patients often have larger blood stasis, and pulmonary interstitial pulmonary edema, lungs costophrenic corner may have interval line, pulmonary vein and pulmonary artery shadow may be extended; pleural effusions uncommon.
ECG in symptomatic patients almost never normal, asymptomatic ECG changes have been a lot of change in cardiac hypertrophy, myocardial damage and cardiac arrhythmias based. Left ventricular hypertrophy more common, often associated with cardiac disorders, often late right ventricular hypertrophy; also may have left or right atrial hypertrophy. myocardial damage common to ST segment depression, T wave flat or inverted phase or as the main performance of the T wave was sometimes ischemic change. a small number of patients with pathologic Q waves can be , similar to myocardial infarction, more than the first interval of its parts (V1, V2 lead), the interval may be the result of fibrosis. heart block common room, left and right bundle branch or left bundle branch block can branch appears. arrhythmia common, especially in the late course, the ectopic rhythm and conduction block based. ectopic atrial rhythm can come from the atrioventricular junction or ventricular, tachycardia by a premature beat and gradually evolved, as well as flutter or fibrillation also has sinoatrial disease, atrioventricular junction escape beat or escape law, or ventricular arrhythmia itself and so on. I-III degree AV block can occur.
Echocardiography in the early stage of the disease to see slight expansion of the cardiac chambers, especially the left ventricle wall motion decreases, later expanded in the heart chamber, left ventricular septal and posterior wall movement is reduced. Mitral valve may disappear before the Ye Shuangfeng The before and after the leaves are different to the activities. spurting percentage of left ventricle to 50% less often, than the number of myocardial shortening is also reduced. may have a small amount of pericardial effusion.
Radionuclide ventriculography can show the heart chamber to expand and reduced wall motion, left ventricular spurting scores decreased more significantly after exercise.
Systolic time early stage is not normal, left ventricular spurting time (LVET) shortening, spurting early (PEP) extension, PEP / LVET increased.
Near-normal early cardiac catheterization, left ventricular end diastolic pressure can be slightly higher. Has heart failure decreased cardiac index, arteriovenous oxygen difference of pulmonary and atrial pressure increased. Cardiovascular Angiography showed expansion of the heart chamber, wall hypokinetic.
