Class IV antiarrhythmics

Class IV antiarrhythmics are composed of calcium channelblockers. The calcium channel blockers verapamil and diltiazem are used to treat supraventricular arrhythmias with a rapid ven-tricular response (rapid heart rate in which the rhythm originates above the ventricles).

For a thorough discussion of calcium channel blockers and how they work, see “Calcium channel blockers,”.
