Supraventricular premature beats mainly include atrial premature beats and atrioventricular junction premature beats, and premature beats are divided into frequent premature beats and episodic premature beats.The number of premature beats in a 24-hour period is greater than 20% of the total number of beats is considered to be frequent premature beats, and less than 10% is considered to be episodic premature beats. The number of premature beats in 24 hours is greater than 20% of the total number of heart beats, and less than 10% of the total number of heart beats is episodic premature beats. Most of the people who have episodic premature beats do not have obvious symptoms, and generally do not need to be treated. 1. Episodic supraventricular premature beats: If there is no organic heart disease and no discomfort, episodic supraventricular premature beats usually do not need treatment, and regular electrocardiogram observation is sufficient. 2. Frequent supraventricular premature beats: If the number of premature beats reaches 10% of the total number of beats in 24 hours and is accompanied by chest tightness, panic and shortness of breath, clinical intervention can be made, and the first choice of antiarrhythmic drugs, such as metoprolol tartrate, propafenone hydrochloride, amiodarone and other treatments. Although all of the above drugs belong to the anti-arrhythmic drugs, but the mechanism and indications are different, you need to choose the most suitable for yourself under the guidance of the doctor.
