Regulation of calcium release is gated by calcium current, not gating charge, in cardiac myocytes

M Näbauer, G Callewaert, L Cleemann, M Morad - Science, 1989 - science.org
In skeletal muscle, intramembrane charge movement initiates the processes that lead to the
release of calcium from the sarcoplasmic reticulum. In cardiac muscle, in contrast, the …

Excitation-calcium release uncoupling in aged single human skeletal muscle fibers
