Introduction Disopyramide is a Class 1a antiarrhythmic agent, primarily used in the treatment of ventricular tachycardia. It functions as a sodium channel blocker, inhibiting conduction by depressing the increase in sodium permeability of cardiac myocytes during the initial phase of the cardiac action potential. This reduces the inward sodium current, leading to an increased threshold…
