Final answer:
Sotalol is used to treat stable ventricular tachycardia, a type of stable wide complex tachycardia, by blocking potassium and beta receptors which regulate heart rate and rhythm.
Step-by-step explanation:
Sotalol is a medication used for the treatment of certain types of tachycardias, particularly those that are deemed to be stable and wide complex. A stable wide complex tachycardia refers to a cardiac rhythm that has a QRS duration of greater than 120 milliseconds and a heart rate exceeding 100 beats per minute, with the patient being hemodynamically stable. Sotalol is indicated for the treatment of stable ventricular tachycardia (VT), a specific type of wide complex tachycardia. This antiarrhythmic medication functions by blocking potassium and beta receptors, which helps to slow down the heart rate and stabilize the rhythm.
