Disopyramide is an antiarrhythmic medication used in the treatment of Ventricular Tachycardia. It is a sodium channel blocker and therefore classified as a Class 1a anti-arrhythmic agent. Disopyramide has a negative inotropic effect on the ventricular myocardium, significantly decreasing the contractility. References: Anzawa R, Ishikawa S, Tanaka Y, Okazaki F, Mochizuki S.
