 We have recently shown that spark termination emerges as collective behavior (synchronized closings) of Ca release channels (RyRs) that is identical to synchronization of spin orientation in ferromagnets described by a phase transition in Ising model . Objective: We employed the Ising approach to investigate and classify mechanisms of spark termination failure and Ca leak.

Objective: We employed the Ising approach to investigate and classify mechanisms of spark termination failure and Ca leak.
 Here we employed both numerical and analytical modeling to get mechanistic insights into the emergent Ca leak phenomenon. Our numerical simulations using a detailed realistic model of Ca release channels (RyRs) that is identical to synchronization of spin orientation in ferromagnets described by a phase transition in Ising model . Objective: We employed the Ising approach to investigate and classify mechanisms of spark termination failure and Ca leak.
