Recurrence after radiofrequency ablation needs to be treated with medication or radiofrequency ablation again, and at the same time, daily care should be done. 1. Drug treatment: If recurrence after radiofrequency ablation occurs, it may lead to arrhythmia and rapid heartbeat, etc. It is recommended to take drugs such as amiodarone hydrochloride tablets and propafenone hydrochloride tablets as prescribed by doctor for treatment. The above medications can relieve the blockage of sodium channels between the myocardium and cardiac conduction, thus relieving the arrhythmia. 2. Re-radiofrequency ablation treatment: Re-radiofrequency ablation treatment needs to be carried out in the hospital after acute electrocardiography and CT examination, according to the examination results and under the doctor’s scientific evaluation. 3. Daily care: usually pay attention to closely observe the heart rate of patients after radiofrequency ablation, adhere to the medication, do not arbitrarily increase or decrease. If there is any discomfort, report to the doctor in time, and do electrocardiogram and color Doppler echocardiography if necessary. The medication should be taken in accordance with the doctor’s instructions, and need to go to the hospital regularly for electrocardiogram examination to clarify the recovery situation.
