Left ventricular hypertrophy, normal blood pressure?
summary
Compared with the right ventricle, the left ventricle is longer and more like a cone. Its cross section also presents an oval or nearly circular outline. The Sternocostal surface, the front of the heart, consists mainly of the right ventricle and a small part of the left ventricle. However, the left ventricle forms not only the apex, but also most of the septum of the heart, which is the side where the organ contacts the diaphragm. To pump blood out at a high blood pressure, the muscles in the left ventricle are thicker and more developed than those in the right ventricle. Let's share my experience with you.
Left ventricular hypertrophy, normal blood pressure?
1. Rheumatic mitral regurgitation: simple rheumatic mitral regurgitation is rare, and most of them are complicated with rheumatic mitral stenosis. On auscultation, the apical part of the heart can be heard with 2 / 6 or above systolic blowing noise, rough, and the first heart sound can be covered up.
2. Aortic regurgitation: causes of aortic regurgitation include rheumatism and syphilis. The former has a younger onset age, mostly between 10 and 40 years old, may have a history of rheumatic fever, has a longer compensatory period of cardiac function, and is often complicated with mitral or aortic stenosis; The onset age of the latter is usually 34-50 years old, with a history of venereal diseases and angina pectoris.
Hypertensive heart disease: the patient has a long history of hypertension, and the heart boundary expands to the left and down. The second tone of aortic valve area is enhanced, and systolic murmur can be heard in the apex due to relative mitral insufficiency.
matters needing attention
Left ventricular hypertrophy is divided into primary and secondary, primary refers to hypertrophic cardiomyopathy, drug therapy includes beta blockers and calcium channel blockers, chemical ablation therapy can achieve good results. Secondary mainly secondary to hypertension, valvular disease, etc., mainly in the treatment of primary diseases.
