This type of drug is most beneficial to patients with premature beats and symptomatic tachycardias. This type of drug can be taken as a long-term treatment by mouth or it can be used in emergency situations when administered intravenously. Antiarrhythmic drugs depress impulse transmission within tissues that are either rapidly conducting or they can help to participate in reentry. These drugs also help to suppress abnormal pacemaker tissue firing. Commonly prescribed antiarrhythmic drugs include Tikosyn, Cordarone, Norpace, Pacerone and Vascor.

This type of drug, also referred to as a blood thinner, is used to reduce blood clotting. This type of drug is most beneficial in treating a type of arrhythmia called atrial fibrillation. Atrial fibrillation puts a patient at a higher risk of developing blood clots so by taking this medication they greatly minimize that risk. Those who already have blood clots can take this type of medication to prevent them from getting bigger. This type of medication can also help to reduce a patient's chance of having a blood clot-related stroke. The most commonly prescribed anticoagulant is Warfarin.
