Experimental evidence for proarrhythmic mechanisms of antiarrhythmic drugs.

abstract：OBJECTIVE:Cardiac parasympathetic nerve activity is reduced in most cardiovascular disease states, and this may contribute to enhanced cardiac sympathetic responsiveness. Disruption of inhibitory G-proteins (Gi) ablates the cholinergic pathway and increases cardiac endothelial nitric oxide (NO) synthase (eNOS) expressi...
