Premature beats are heart beats caused by premature impulses from ectopic pacing points and are the most common arrhythmia. Premature beats are classified as atrial, ventricular, or nodal depending on the site of origin. Ventricular premature contractions are the most common, followed by atrial and, less frequently, nodal contractions. Premature beats can be seen in normal subjects or in patients with organic heart disease, such as coronary heart disease, rheumatic heart disease, hypertensive heart disease, cardiomyopathy, etc. They can also be induced by quinidine, procainamide, digitalis or antimony poisoning; low potassium and hyperthyroidism; mechanical stimulation of the heart during cardiac surgery or cardiac catheterization, etc. Premature beats can also be induced. If premature beats occur in individuals with a heart without organic pathology, they generally do not increase their mortality rate and are not clinically significant, regardless of their form and frequency, and no further treatment is necessary. Premature contractions are of concern in the following cases: 1) in cases of myocardial ischemia or myocarditis; 2) in cases of hypokalemia; 3) in cases of cardiotoxic drug intoxication; 4) in cases of organic heart disease. In cases of premature beats associated with organic heart disease, the original cause should be treated. For ventricular premature contractions caused by digitalis toxicity. In addition to withdrawal of the drug, intravenous phenytoin sodium or intravenous potassium chloride infusion is often effective. For premature beats caused by low potassium, the cause should be actively removed and the hypokalemia should be corrected. There are many reasons for premature beats, so bad habits, mental stimulation and other factors can cause them, so pay attention to them, adjust their diet and life, and actively treat them to avoid causing harm to the body, so what should you do when this happens? Prevention of premature beats: 1. Don’t be nervous when this condition is found, don’t be overly nervous, identify the cause further and clarify the severity, the prognosis of the vast majority of patients with premature beats is good. 2. Frequent premature beats For patients with heart disease based on possible complications of heart rhythm disorders, leading to angina pectoris and heart failure, timely treatment is required. 3.Episodic premature beats For occasional cases, when the effect on blood circulation is not significant and will not cause other diseases, treatment is generally not necessary, so the patient should eliminate ideological concerns and maintain optimism. 4.Living habits To correct bad habits, such as smoking, drinking, uncontrolled diet and overeating. Do not eat stimulating food, pay attention to more rest, combine work and rest, and insist on exercising. This is the introduction to the prevention of premature beats, I hope the above-mentioned content will help you, usually to develop good habits, regular diet, maintain emotional stability, do not overwork, moderate exercise. To enhance the body’s immunity.
