[Cardiac excitation-contraction coupling mediated by Ca2+]

Abstract

Cardiac excitation-contraction coupling is the process which links electrical excitation of the cardiac myocytes with heart contraction. Of the ions involved in cardiac excitation-contraction coupling, calcium is considered to be the essential and crucial factor. In this short communication, we will briefly illustrate how calcium is involved in excitation-contraction coupling in order to better understand the heart function.
