Premature beats can be categorized into pathological and physiological, and the need for treatment should be determined on a case-by-case basis. The normal beating of the heart is initiated by the sinus node, while premature beats are caused by the premature impulse of the ectopic pacing point, which is the most common arrhythmia, such as coronary artery disease, myocarditis, mitral valve lesions and so on, premature beats often occur, and the patient should find out the cause of triggering as soon as possible, and give the cause of the treatment. Certain non-disease factors, such as high mental stress, excessive smoking, drinking alcohol, drinking coffee, etc., can also trigger premature beats, such patients usually do not need special treatment, pay attention to ease the mood, quit smoking and drinking, avoid drinking strong tea, coffee and other stimulating beverages, generally can be recovered on their own. If premature beats occur frequently, patients should consult the cardiovascular medicine department in time for electrocardiogram, cardiac ultrasound and other examinations to clarify the cause of the disease. At the same time, it is necessary to pay attention to daily rest, avoid high salt and high fat diet.
