Synchronization of Stochastic Ca(2+) Release Units Creates a Rhythmic Ca(2+) Clock in Cardiac Pacemaker Cells

In sinoatrial node cells of the heart, beating rate is controlled, in part, by local Ca(2+) releases (LCRs) from the sarcoplasmic reticulum, which couple to the action potential via electrogenic Na(+)/Ca(2+) exchange. We observed persisting, roughly periodic LCRs in depolarized rabbit sinoatrial nod...
