Not all premature atrial contractions require oral medication. For example, if a patient has only episodic premature atrial contractions, which are caused by lack of rest, frequent exertion, or mental stress, medication is not needed, and the patient is advised to pay more attention to rest, avoid drinking strong tea and coffee, and relax more, gradually the premature atrial contractions will disappear. However, if the patient has frequent atrial presystole, and the patient is accompanied by very uncomfortable symptoms. It is recommended that patients can first take oral beta-blockers, representative drugs such as metoprolol and bisoprolol. If atrial premature does not improve significantly after taking this type of antiarrhythmic drugs, one can also choose to take oral propafenone or amiodarone to improve atrial premature, but such drugs as propafenone or amiodarone have relatively more side effects.
