Which term describes a drug that controls irregular heartbeat?

Explanation:
Drugs that regulate heart rhythm are called antiarrhythmic agents. These medications work by altering the electrical properties of cardiac tissue to suppress abnormal impulses, stabilize conduction, and adjust refractoriness, helping restore a normal heartbeat. They’re grouped by mechanism (sodium channel blockers, beta-blockers, potassium channel blockers, calcium channel blockers), each addressing different rhythm disturbances. The other terms describe drugs for non-cardiac uses—antiamoebic for amoebic infections, anthelmintic for parasites, and ambroxol as a mucolytic. Thus, the term for a drug that controls irregular heartbeat is antiarrhythmic.
