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 |
