Which medications are used to correct electrical irregularities of the heart?

The use of antiarrhythmics or antidysrhythmics is specifically aimed at correcting electrical irregularities in the heart. These medications work by targeting the heart's rhythm and preventing or treating arrhythmias—conditions where the heart beats too fast, too slow, or irregularly.

Antiarrhythmics can modify the electrical conduction in the heart, thus restoring a normal rhythm and helping to stabilize the heart's activity. They include drugs that influence various ionic channels and receptors that are crucial for the conduction of electrical impulses within the heart.

In contrast, the other options focus on entirely different therapeutic areas. Antibacterials are used to treat bacterial infections, antigout medications target uric acid symptoms associated with gout, and antimigraine medications are aimed at preventing or alleviating migraine headaches. Each of these categories serves specific health issues unrelated to the electrical functions of the heart.
