When the heart contracts, the anterior wall of the left ventricle strikes the chest wall in the precordial region early in systole, causing the corresponding part of the rib question tissue to pulsate outward, called apical pulsation. After myocardial infarction of the left ventricle, the entire myocardium of the ventricular wall is necrotic. In about 10-38% of cases, the necrotic myocardium is gradually replaced by fibrous scar tissue, forming a ventricular wall tumor. The thin layer of the ventricular wall in the lesioned area bulges outward, and the heart loses mobility or shows paradoxical motion during contraction. The evolution of coronary artery obstruction, myocardial infarction, myocardial fibrosis and left ventricular ventricular wall tumors was well understood as early as 1881. Patients with inverse beats are advised to eat foods rich in vitamins and mineral elements, foods rich in high quality protein, and foods that are easy to digest. The following foods are recommended to be eaten in moderation: 1, tomatoes tomatoes have the effect of reducing blood lipids, but also has a stomach, thirst, laxative, anti-blood suspicion aggregation, anti-brain thrombosis and other effects.
