Elderly people with atrial fibrillation (AF) with a heart rate of 110 beats per minute can be treated with medication, catheter ablation and other means, and attention should be paid to the prevention and treatment of complications. 1. Drugs to reset the rhythm: atrial fibrillation is a common arrhythmia, the elderly atrial fibrillation acute attack, you can use amiodarone or propafenone, quinidine these drugs to reset the rhythm, in order to restore the normal sinus rhythm. For patients who cannot be reset, the ventricular rate needs to be controlled below 100 beats/min, commonly used drugs include digoxin, metoprolol, diltiazem and so on. 2. Catheter ablation: Catheter ablation can be considered for atrial fibrillation that cannot be reset by drugs. It is necessary to take into account the medical history of the elderly and the size of the left atrium to decide whether it meets the indications for surgery. 3. Prevention and treatment of complications: In patients with permanent atrial fibrillation, wall thrombi are easily formed. In the non-acute episodes of drug should be anticoagulation therapy, conventional drugs are warfarin and new oral anticoagulants such as rivaroxaban, dabigatran, etc. For valvular atrial fibrillation, it is recommended to take warfarin anticoagulation, and closely monitor coagulation during the period of taking the drug. The severity of the symptoms of atrial fibrillation in the elderly is affected by the rapidity of the ventricular rate, and patients may experience angina pectoris and congestive heart failure. When the ventricular rate is not fast, the patient may be asymptomatic, and it is only recognized when serious complications occur. Most patients feel symptoms such as panic, dyspnea, chest pain, fatigue, dizziness and blackouts. The above medicines need to be used under the supervision of a doctor.
