The treatment of atrial fibrillation should consider the following four aspects. The first is rhythm conversion, the second is ventricular rate control, the third is to maintain a normal rhythm, the fourth is anticoagulation to prevent thrombosis. 1, rhythm conversion, the first time atrial fibrillation is found, generally speaking, to see if it can be converted to a normal rhythm, rhythm conversion can be used drugs can also be used electrical resuscitation. 2, control the ventricular rate, some old atrial fibrillation often occur atrial fibrillation, or older will not consider rhythm conversion, that is, the ventricular rate do not let it beat too fast. Some people will be very upset when it reaches 150 or 160 times, so they can control the ventricular rate below 140. If it happens occasionally, every few years, or once in many years, it may not be necessary to take medication to maintain a normal rhythm. 4, anticoagulation, prevention of thrombosis, if atrial fibrillation occurs for more than 1 or 2 days, the risk of thrombosis increases greatly, at this time, anticoagulants must be used to prevent thrombosis caused by atrial fibrillation.
