Maintenance of resting potential in anoxic guinea pig ventricular muscle: electrogenic sodium pumping.

T F McDonald, D P MacLeod.   

Abstract

Anoxic ventricular muscle maintained a normal resting potenitial despite a large loss of potassium. The resting potential was separated into two components: one that depended on the potassium distribution, and one that depended on the activity of an electrogenic sodium pump.
