The current medications for atrial fibrillation mainly include three types: the first type controls the ventricular rate, which ensures the basic function of the patient's heart and minimizes the cardiac dysfunction caused by atrial fibrillation. This includes drugs such as receptor blockers and calcium channel antagonists, digoxin, amiodarone, and others. The second type of drugs are those used for cardioversion. The third type of drugs are those used to prevent embolism, which are anticoagulants. Currently, the main drugs include warfarin, new anticoagulants such as dabigatran and rivaroxaban, and intravenous medications like low molecular weight heparin calcium and nadroparin.
