If arrhythmia is caused by ventricular premature beats or atrial premature beats, β -blockers such as metoprolol or bisoprolol can be used to reduce heart rate and cardiac output and reduce heart load. If it is arrhythmia caused by atrial fibrillation, we can use amiodarone to restore sinus rhythm, and then take warfarin for a long time to prevent cerebral infarction caused by thrombosis. However, patients taking such drugs should regularly check their blood routine and coagulation function to avoid bleeding due to abnormal coagulation function. If it is arrhythmia caused by coronary heart disease, you can take drugs that dilate coronary arteries and stabilize plaques, such as nitroglycerin and atorvastatin. If it is ventricular tachycardia or idiopathic ventricular tachycardia, radiofrequency ablation can be considered for radical treatment. If the elderly themselves have no organic pathological changes, but arrhythmia caused by drug action or autonomic nerve dysfunction, symptoms can be relieved by stopping taking drugs and improving bad emotional stimulation.
