What is premature heart beat?

Premature contraction is an ectopic rhythm that occurs outside the normal sinus rhythm of the heart. Premature

contraction may be an ectopic arrhythmia originating from the sinus node, or from the atria, atrioventricular nodes, or ventricles. Premature contraction may be related to factors such as excessive fatigue, mental stress, excessive drinking of coffee or tea, or may be caused by diseases such as myocardial infarction, cardiomyopathy, and valvular disease. Patients may experience palpitations, palpitations, and cardiac arrest.

Patients can be treated with drugs such as bisoprolol, nifedipine, and propafenone under the guidance of a doctor to relieve arrhythmia. They can also be treated with radiofrequency ablation through a catheter to control the condition.
