Oscillatory after-potentials and triggered-automaticity in mammalian ventricular muscle fibres at high resting potentials.

M Hiraoka, Y Okamoto, T Sano.   

Abstract

Oscillatory after-potentials and triggered-automaticity were observed in dog ventricular muscle fibres when the fibres were exposed to K+-free,high-Ca++-solutions after K+-free,Ca++-free perfusion. They appeared at membrane potentials more negative than--60 m V.
