Medical Treatment of Ventricular Arrhythmias

Abstract

Medication is not always necessary when a patient with ventricular arrhythmia is asymptomatic. The use of antiarrhythmic drugs is based on underlying cardiac diseases. In general, antiarrhythmic drugs with Na⁺ channel blockers impair cardiac contractility. Therefore, the selection of antiarrhythmic drugs in patients with cardiac dysfunction needs special consideration.
