Cardiac Arrhythmia & Treatment

tachycardias, premature beats treated with a variety of antiarrhythmic drugs

Symptomatic tachycardias and premature beats may be treated with a variety of antiarrhythmic drugs. These may be given intravenously in an emergency situation or orally for long-term treatment. These drugs either suppress the abnormal firing of pacemaker tissue or depress the transmission of impulses in tissues that either conduct too rapidly or participate in reentry.

In patients with atrial fibrillation, a blood thinner (anticoagulant or antiplatelet agent such as aspirin) is usually added to reduce the risk of blood clots and stroke.
