For 70-year-olds who find themselves with atrial fibrillation, medication may be more of a consideration. After all, patients are too old to undergo surgery, so there is nothing wrong with considering medication. The first consideration is whether or not the rhythm can be restored. If the rhythm is not successfully restored with medication, it will be a question of whether or not to operate. Although the patient is 70 years old, there are in fact minimally invasive methods of atrial fibrillation treatment, such as radiofrequency ablation via catheter in internal medicine, which for many patients may not require general anesthesia and can be done under local anesthesia. If the patient’s physical condition is good enough, surgical radiofrequency ablation can also be considered, or combined medical and surgical radiofrequency ablation treatment. Of course, if there is no way to restore sinus rhythm, you can consider controlling the patient’s rapid ventricular rate so that the patient’s subjective symptoms of discomfort can be relieved. Patients must take anticoagulants to prevent thrombosis and the formation of a stroke.
