Abstract: Abstract: Cardiac arrhythmias are varied and very common. They are usually classified as bradyarrhythmias and tachyarrhythmias, which are treated according to their own common principle separately. There is no long term effective oral drugs that can be used to treat bradyarrhythmias effectively up to now. Pacemaker is still the only effective treatment for it. Now catheter ablation has already applied to almost every kind of tachyarrhythmias, and which is the first choice for treating supraventricular tachycardia and atrial flutter because of the satisfactory result. Most patients with other types of tachyarrhythmias, especially atrial fibrillation and all kinds of premature beats are still given drug therapy. Amiodarone, propafenone, sotalol and mexiletine are common used antiarrhythmic drugs in our country. This article overviewed the principle and the matters need to attention in the drug therapy of cardiac arrhythmias.
