Description and Uses
Verapamil, the classic calcium antagonist, has a negative inotropic, anti-ischemic, and conduction-delaying effect on the heart , . Its antiarrhythmic effect is based primarily on a prolongation of impulse conduction time in theAVnode and a reduction of frequency of impulse generation in the SA node.
Verapamil is primarily used as an antiarrythmic for treating ventricular arrhythmias; however, currently it is being forced out gradually by adenosine.
