Sinoatrial Node Impulses Emerge From Incessant, Unique Kinetic Transitions In Disordered Local Calcium Dynamics

Syevda Tagirova, Alexander V. Maltsev, Georgiana Luisa Baca, Victor A. Maltsev, Rostislav Bychkov, Edward G. Lakatta

The paper analyzes local calcium dynamics in mouse sinoatrial node cells to show how stochastic transitions in heterogeneous calcium oscillations generate rhythmic impulses.
