Ontology: Anti-Arrhythmia Agents (C0003195)

Definition (NCI) Agents used for the treatment or prevention of cardiac arrhythmias; they may effect the polarization-repolarization phase of the action potential, its excitability or refractoriness, or impulse conduction or membrane responsiveness within cardiac fibers.(CRISP)
Definition (MSH) Agents used for the treatment or prevention of cardiac arrhythmias. They may affect the polarization-repolarization phase of the action potential, its excitability or refractoriness, or impulse conduction or membrane responsiveness within cardiac fibers. Anti-arrhythmia agents are often classed into four main groups according to their mechanism of action: sodium channel blockade, beta-adrenergic blockade, repolarization prolongation, or calcium channel blockade.
Definition (CSP) group of agents used for the treatment or prevention of cardiac arrhythmias; they may effect the polarization-repolarization phase of the action potential, its excitability or refractoriness, or impulse conduction or membrane responsiveness within cardiac fibers.
