Abstract

It is generally accepted that certain cardiac rhythm disturbances are due to imbalances between the sympathetic and parasympathetic nervous systems. We have provided evidence that digoxin is concentrated in the peripheral nervous system of the heart as well as in the central nervous system. Previous findings have indicated that cardiac glycosides may directly or indirectly affect autonomic neurotransmitters. Therefore the uptake of digoxin into the peripheral cardiac nervous system may play an important role in both the antiarrhythmic and toxic electrophysiologic actions of digoxin.
