Episodic atrial premature beats are usually not considered a heart disease, and they can occur in normal people. Episodic atrial premature beats usually do not require treatment. When symptoms become apparent, they should be seen in a hospital promptly to avoid adverse consequences. Atrial premature beats, also known as atrial pre-systole, are atrial agitation originating anywhere in the atria other than the sinus node. The main clinical manifestation of atrial premature beats is palpitations, some patients may have symptoms such as chest tightness, fatigue, and consciously feel a sense of stopping, and some patients may not have any symptoms. Atrial premature beats are mostly functional and occur in most normal people within 24 hours. The incidence of atrial premature contractions can be greatly increased in patients with organic heart disease such as coronary artery disease, pulmonary artery disease, and cardiomyopathy.
