The Nav1.5 late current in WT and Nav1.5 ΔKPQ mutant channels: An automated patch-clamp LQT3 electrophysiological assay

Poster Description

The cardiac late Na+ current (late INa) generates persistent inward currents throughout the plateau phase of the ventricular action potential and is an important determinant of repolarisation rate, EADs and arrythmia risk. As inhibition of late INa can offset drug effects on hERG and other repolarising K+ conductances it is one of the key cardiac channels in the Comprehensive in vitro Proarrythmia Assay CiPA panel being developed by the FDA to improve human clinical arrythmia risk assessment.
