Can episodic atrial premature beats cause sudden death?

Episodic atrial premature beats are not usually associated with sudden death. Atrial premature beats, also known as atrial pre-systoles, are ectopic beats originating in the atria that occur earlier than the next sinus heartbeat, and the accompanying compensatory intervals are usually incomplete. Depending on the frequency of premature beats, five or fewer per minute are called episodic atrial premature beats and are common in clinical practice. Atrial premature beats can be seen in normal individuals, in the presence of physiologic stimuli such as sympathetic nerves, or in the presence of cardiac and systemic pathologies. They may be asymptomatic or may be associated with symptoms such as palpitations and chest tightness, and the diagnosis is based on an electrocardiogram (ECG) or 24-hour ambulatory electrocardiogram (ECG) recording. Episodic atrial premature beats are usually uncomplicated, have a relatively minor hemodynamic impact, and do not lead directly to sudden death. The prognosis of patients with episodic atrial premature beats in the absence of organic heart disease is favorable after lifestyle modification. If the symptoms are severe and the symptomatic treatment is ineffective, antiarrhythmic drugs can be used appropriately, and those with organic heart disease should actively treat the underlying disease. Patients with episodic atrial premature beats should complete the relevant examinations under the guidance of the doctor to exclude organic heart diseases and carry out treatment according to the doctor’s instructions.
