Electrochemical Na(+) and Ca(2+) gradients drive coupled-clock regulation of automaticity of isolated rabbit sinoatrial nodal pacemaker cells

Coupling of an intracellular Ca(2+) clock to surface membrane ion channels, i.e., a “membrane clock, ” via coupling of electrochemical Na(+) and Ca(2+) gradients (E(Na) and E(Ca), respectively) has been theorized to regulate sinoatrial nodal cell (SANC) normal automaticity. To test this hypothesis,...
