Summary of Drug Classes Used in the Treatment of Arrhythmias

The following table summarizes which antiarrhythmic drugs can be used to treat different arrhythmias. The information was derived primarily from UpToDate on 9/6/22. It is important to note that for a given condition, a particular drug may not be efficacious, and in fact, it may precipitate other arrhythmias or adverse cardiovascular effects (e.g., cardiac depression, hypotension). Therefore, drug efficacy and safety must be carefully evaluated and individualized to the patient when treating arrhythmias.
