Premature cardiac beats include atrial premature beats, ventricular premature beats, and atrioventricular junctional premature beats, etc. Ablation does not usually affect life expectancy. Premature heart beats can affect the normal rhythm of the heart and aggravate myocardial ischemia, and the persistence of premature beats over a long period of time may lead to cardiac insufficiency. For a large number of premature beats that are ineffective in drug treatment, radiofrequency ablation can be performed. Radiofrequency ablation is a minimally invasive therapeutic technique, which has little damage to the heart and fewer complications, and does not generally have an impact on survival time. Radiofrequency ablation bed is mainly used for the treatment of arrhythmia, premature beats is one of the indications, but also for the treatment of supraventricular tachycardia, ventricular tachycardia. The main principle of radiofrequency ablation is localized heating, which destroys the abnormal conduction system of the heart and eliminates the abnormal conduction. Patients with cardiac arrhythmias should clarify whether there is an indication for radiofrequency ablation under the guidance of a physician, and ablation therapy can be performed if there is an indication.
