Premature beats and atrial fibrillation which is serious

Atrial fibrillation is atrial fibrillation, which is usually more severe than premature beats.

Premature beats are extra heart beats outside of the normal heartbeat rhythm, usually feeling like beats and jerks. In most cases, premature beats are harmless arrhythmias that require only observation and appropriate lifestyle management. Atrial fibrillation is a common type of cardiac rhythm disorder. Rapid and irregular contraction of atrium on the heart belongs to serious arrhythmia, which may increase the risk of complications such as stroke and heart failure. The prognosis is relatively poor, so premature beat is lighter than atrial fibrillation.
