Atrial fibrillation ablation may cause cardiac distress for a short period of time, and there is a possibility of cardiac ejection insufficiency and arrhythmia after the procedure, which can lead to symptoms such as panic and palpitations. If atrial fibrillation is not cured after radiofrequency ablation, patients with atrial fibrillation will still have symptoms of cardiac ejection insufficiency such as panic and weakness before the operation. If atrial fibrillation has been converted to sinus, the symptoms of cardiac ejection insufficiency will generally be reduced, but a few patients still have tachycardia and other cardiac arrhythmias, which will be manifested as symptoms such as panic and palpitations. If atrial fibrillation is not corrected after radiofrequency ablation, it is recommended that a second radiofrequency ablation procedure may be chosen under the guidance of a physician. If atrial fibrillation has been converted to sinus, anticoagulants such as warfarin or dabigatran should be given routinely to prevent embolism; if there is sinus tachycardia, it is recommended to give amiodarone or β-blocker to stabilize the heart rate. If there is any discomfort after radiofrequency ablation, it is recommended to consult a doctor in time and treat under the doctor’s guidance, and not to take medication without authorization.
