Atrial premature beats can be asymptomatic in some people and symptomatic in others, mainly characterized by palpitations and chest tightness. Premature cardiac contractions are asymptomatic and are usually detected by an electrocardiogram (ECG) during a physical examination. In normal adults who undergo a 24-hour ambulatory electrocardiogram (EKG), atrial premature contractions may occur in about 60% of the population. They are mostly functional and usually do not require treatment. Symptoms may include palpitations, chest tightness, fatigue, and conscious cardiac arrest. Symptoms are mostly non-specific, if the above symptoms or obvious discomfort, can be treated with medication, commonly used therapeutic drugs, including beta-blockers (bisoprolol, metoprolol, etc.), non-dihydropyridine calcium blockers (diltiazem, verapamil, etc.), propafenone, amiodarone, and so on. If there is any discomfort, consult the doctor in time, and the medication should be rationally applied according to the doctor’s prescription.
