Herg safety assay

141    

ICH S7B guideline1 regulates in vitro IKr assay (such as hERG safety assay) and in vitro QT assay for identifying and assessing the potential of a test compound to delay ventricular repolarization. Ventricular repolarization is a complex physiological process determined by the duration of the cardiac action potential. It is the net result of the activities of many highly interdependent membrane ion channels and transporters.
