Antiarrhhythmic Agents
Mnemonic for Class I-IV agents:
SoBe PoCa (SOBE as in South Beach or the drink, POCA as in Polka)

Sodium channel blockers, Beta blockers, Potassium channel blockers, Calcium channel blockers
Class I agents
interfere with the
sodium (Na+) channel.
Indications for Class Ia agents are supraventricular tachycardia, ventricular tachycardia, symptomatic ventricular premature beats, and prevention of ventricular fibrillation
Class II agents
are anti-sympathetic nervous system agents. All agents in this class are beta blockers.
Class III agents
affect potassium (K+) efflux.
Class IV
agents affect the AV node.
Class V
agents work by other or unknown mechanisms, give example
Ex of Ia
given bec
agents include quinidine, procainamide and disopyramide


Indications for Class Ia agents are supraventricular tachycardia, ventricular tachycardia, symptomatic ventricular premature beats, and prevention of ventricular fibrillation
