Antiarrhythmic APIs are a class of compounds used to prevent and treat tachycardia arrhythmias, such as atrial fibrillation, ventricular tachycardia, and supraventricular tachycardia. These compounds work by targeting electrical signals in the heart, helping to regulate the heart rhythm and return it to a normal, steady beating.
