Atrial premature beats are atrial pre-systoles, which are one of the most common types of arrhythmia. Atrial premature beats originate in any part of the atrium other than the sinus node, and some patients have no symptoms, while others experience palpitations, a sense of heart “stopping”, accompanied by chest tightness, dizziness and fatigue, and an intermittent pulse. Atrial premature beats can be divided into physiologic and pathologic. Physiologic atrial premature beats are mostly seen in middle-aged and elderly people, and are related to sympathetic hyperactivity caused by autonomic dysfunction. Factors such as high mental tension, over-excitement, drinking strong tea, coffee, alcohol and staying up all night may cause atrial premature beats. In addition, some people may also experience atrial premature beats after strenuous exercise. Physiologic atrial premature beats do not require treatment, and most patients’ heart rates can return to normal on their own after removing the triggers. Pathologic atrial premature beats are often associated with organic heart disease, such as coronary heart disease, rheumatic heart disease, myocarditis, cardiomyopathy, heart valve disease and so on. In addition, drug intoxication, electrolyte disorders, hyperthyroidism, etc., may also cause atrial premature beats. Pathologic atrial premature beats need to take effective treatment measures for the primary disease. When atrial premature beats cause atrial fibrillation, atrial flutter, supraventricular tachycardia, etc., antiarrhythmic drugs are needed. Beta-blockers, such as atenolol and metoprolol, are often chosen, and calcium antagonists, such as verapamil, can also be used. It is recommended that the correct medication be used for treatment under the guidance of a doctor, and not blindly used on your own.
