ABSTRACT
In cardiac myocytes, Ca 2+ sparks origining fr om a single RyR or a few RyRs are triggered by a single L-type Ca 2+ channel or occur spontaneously. Ca 2+ sparks constitute the elementary local Ca 2+ release events from the SR. Ca 2+ sparks occur at Z-lines and rando mly distribute at different locations, the characteristics of the kinetics are r egulated by many factors. In addition, I Ca.T, Na+/Ca 2+ exchang e, I Ca(TTX) and IP 3 are other putative sources of Ca 2+ that tr igger SR Ca 2+ release.
