The chance of recurrence after radiofrequency ablation of premature beats varies from person to person and cannot be generalized. Premature beats, i.e., preterm contractions, are caused by ectopic pacing points in the heart that release electrical impulses in advance. Occasional premature beats can be left untreated by avoiding triggering factors and following up regularly. Frequent premature beats will affect the cardiac function, it is recommended to actively treat, when the effect of drug control is unsatisfactory, radiofrequency ablation can be adopted. However, after radiofrequency ablation, any type of premature beats may recur in the future, because new ectopic pacing points may form in other parts of the heart, and the symptoms of premature beats will occur again. The more severe the symptoms of premature beats before treatment, the higher the probability of recurrence after treatment. Patients with coronary artery disease, myocardial infarction, hypertrophic cardiomyopathy, myocarditis and other diseases will also have a higher probability of recurrence of premature beats after radiofrequency ablation. The probability of recurrence is also higher in patients who do not take antiarrhythmic drugs after the procedure. Therefore, it is recommended that patients with premature beats should have regular checkups after radiofrequency ablation, follow the doctor’s instructions for treatment, and avoid all kinds of triggering factors, so as to minimize the chance of recurrence.
