WebContractility is often used to characterize the mechanical properties of induced pluripotent stem cell-derived cardiomyocytes and to detect the effects of compounds on cardiac contractile function (e.g. inotropes). Measures such as beat amplitude, beat period, and excitation-contraction delay reveal changes in contractile function due to ...
