Effects of palytoxin on the electrical activity of dog and rabbit heart.

S Weidmann.   

Abstract

Reversible effects of palytoxin, extracted from colonies of the soft coral Palythoa caribaeorum, are described. There is a decrease of both membrane resting potential and overshoot during activity. Rise time of the action potential is prolonged, while repolarization is shortened. The electrical events resemble those seen with metabolic poisons.
