Premature beats can also occur in normal people. The appearance of premature beats after RF ablation requires identification of whether they occur after RF ablation or whether they were present before the procedure. In the case of supraventricular tachycardia ablation, the onset of supraventricular tachycardia is usually triggered by premature beats, and RF ablation only solves the corresponding conduction problem, not the premature beats. There are also patients who have undergone radiofrequency ablation for premature ventricular tachycardia or ventricular tachycardia, but may still have premature beats after the procedure, so they need to be alert to the possibility of recurrence of the disease or the emergence of other problems after the disease has been cured. In addition, the most frequently done radiofrequency ablation of atrial fibrillation, patients with premature beats are more common. This condition is called early onset arrhythmia within 3 months, and the discovery of arrhythmia, which we call the blanking period, will lead to premature beats, atrial tachycardia, and atrial fibrillation, which are considered clinically observable and have no particular clinical value for disease recurrence and prognosis. Therefore, premature beats should be diagnosed discriminately, and the specific situation can be communicated with the surgeon to confirm whether the premature beats are related to radiofrequency ablation or combined with the disease condition itself.
