Premature atrial arrhythmias require treatment when they are clearly symptomatic or when they induce other tachyarrhythmias. Atrial premature contraction needs to be treated when there are obvious symptoms, when the dynamic electrocardiogram suggests that it is too frequent, or when it is combined with organic heart disease. 1. Atrial premature contraction is also known as atrial pre-systole, most patients can be asymptomatic, occasionally panic, some patients have chest tightness, fatigue symptoms. Atrial premature contraction generally does not require treatment. In the case of obvious symptoms or atrial premature induced other tachyarrhythmias, corresponding treatment must be carried out. Commonly used drugs in the clinic are β-blockers, propafenone and so on. 2.Ventricular premature, also known as ventricular pre-systole, the need for treatment depends on the symptoms, whether it is combined with organic heart disease and the number of premature beats throughout the day as indicated by the dynamic electrocardiogram. If there is no organic heart disease and the ventricular premature beats are less than 1,000 per day, there is no need for medication if there are no obvious symptoms or if the symptoms are mild. If the patient’s symptoms are obvious, or the premature beats are between 1000-10000 times, oral antiarrhythmic drugs can be taken, including moresizine or mesylate, etc. In mild cases, oral beta-blockers or traditional Chinese medicines such as ginseng pine heart capsule, stabilizing heart granules, etc. can be taken. Monomorphic premature ventricular beats all day >10000 times, the effect of drug treatment is not good, can consider minimally invasive intervention of radiofrequency ablation surgery. Organic heart disease combined with premature ventricular beats, mainly for the treatment of the primary disease, such as more serious symptoms or more premature beats, can use beta-blockers, amiodarone and so on. Need to be under the guidance of the doctor, avoid unauthorized use of drugs.
