There is no optimal time for radiofrequency ablation, but it depends on the needs of the patient and his/her physical condition. Cardiac catheterization radiofrequency ablation is a method of treating arrhythmia by introducing radiofrequency electric current (a kind of high-frequency electromagnetic wave) into the heart through a cardiac catheter in order to ablate localized cardiac myocytes in a specific area, to ablate the refractory loops, or to eliminate the abnormal foci. Radiofrequency ablation is a minimally invasive procedure mainly used for the treatment of arrhythmia. Before the procedure, the patient’s overall condition should be assessed, whether the condition requires it, whether the body can tolerate it, and the exact timing of the radiofrequency ablation procedure should be advised by a specialized doctor. Any treatment varies from person to person, it is recommended to go to the hospital in time and under the guidance of the doctor.
