Beat-to-Beat Variation in Periodicity of Local Calcium Releases Contributes to Intrinsic Variations of Spontaneous Cycle Length in Isolated Single Sinoatrial Node Cells

Spontaneous, submembrane local Ca(2+) releases (LCRs) generated by the sarcoplasmic reticulum in sinoatrial nodal cells, the cells of the primary cardiac pacemaker, activate inward Na(+)/Ca(2+)-exchange current to accelerate the diastolic depolarization rate, and therefore to impact on cycle length....
