Arrhythmias (or changes from the normal sequence of electrical impulses, causing abnormal heart rhythms) are often treated and managed using medication. Designed to suppress arrhythmias by treating their underlying cause, preventing conditions that contribute to arrhythmias, and managing arrhythmia symptoms, these medications include a category of drugs referred to as anti-arrhythmic agents, beta-blockers, calcium channel blockers, and digitalis.

Careful dosing of anti-arrhythmic agents is essential, as these medications have a narrow toxic-therapeutic relationship. In other words, a dosage that produces beneficial effects may cause serious complications in slightly higher or lower doses.
