A Privileged Role For Neuronal Na+ Channels In Regulating Ventricular [Ca2+] And Arrhythmias

In cardiac myocytes, electrical signaling and Ca2+ signaling are closely coupled. Electrical signals, in the form of action potentials, produce periodic increases and decreases in intracellular [Ca2+]—so-called “Ca2+ transients”—and these Ca2+ signals can, in turn, influence action
