Coronary heart disease is the first major disease causing human death, recognize the existence of their own risk factors for cardiovascular disease, the implementation of self-care, is responsible for their own health, the following set of charts to give you a more intuitive understanding of cardiovascular disease! [The danger of hypertension] Hypertension is a killer of human health, can be accompanied by a variety of diseases, its main hazards are stroke, myocardial infarction, blindness, heart failure and kidney failure. [Three Common Conditions of Coronary Heart Disease] Coronary heart disease is the number one cause of human death and can be clinically categorized into three types: atherosclerosis with blood clots, atherosclerosis and coronary artery spasm. 【Common Anti-Arrhythmic Drugs】 There are many types of arrhythmia, such as sinus bradycardia, ventricular arrhythmia, and stress-induced. When treated with medication, atropine is the main treatment for sinus bradycardia; digoxin can treat supraventricular arrhythmias …… 【AV block】 Abnormal electrical excitation conduction that occurs between the atria and the ventricles during electrical excitation conduction of the heart can lead to arrhythmia, which prevents the heart from contracting and pumping blood normally, and is known as atrioventricular conduction block. If a normal sinus rhythm is compared to a car, then the following are the conditions in which the heart induces AV block. Coronary Heart Disease Intervention】 Coronary heart disease is mainly caused by coronary artery thrombosis, blocking the blood and oxygen supply to the human heart muscle. Interventional therapy for coronary heart disease is a treatment method that effectively improves myocardial blood flow and perfusion by unblocking narrowed or even occluded coronary arteries through cardiac catheterization techniques, such as coronary artery bypass grafting and stent implantation, which are common. Typical electrocardiographic manifestations of electrolyte disorders] Electrolyte disorders refer to the increase and decrease of serum electrolyte concentration, which will affect myocardial depolarization and repolarization and abnormal agonist conduction, and can be reflected in the electrocardiogram. Clinical manifestations of left heart failure and right heart failure] Heart failure can be categorized into left heart failure and right heart failure with different clinical manifestations. [Cardiac Auscultation] The heart has different auscultation zones, usually starting from the mitral valve area and ending at the tricuspid valve area.
