Cardiac radiofrequency ablation can be done several times, but if it is not effective after several consecutive sessions, it is not recommended to continue radiofrequency ablation for a short period of time.
Radiofrequency ablation is mainly applicable to supraventricular tachyarrhythmias, such as atrial fibrillation and atrial flutter effectively, and ventricular arrhythmias, such as ventricular premature and ventricular tachycardia, which can be performed several times. However, recurrence soon after successive procedures indicates that this patient’s condition is complex and not suitable for radiofrequency ablation, such as taking amiodarone or metoprolol can control the ventricular rate, it is recommended to take medication first, and radiofrequency ablation can be performed again after a period of time according to the doctor’s instructions.
Cardiac radiofrequency ablation is an interventional procedure in which an electrode catheter is sent into a specific part of the heart chambers through the femoral artery by minimally invasive puncture to release the electric current, which causes coagulative necrosis of the endocardium and subendocardial myocardium under the part, so as to achieve the purpose of blocking the abnormal discharge point of tachyarrhythmia and electrical conduction bundles.
