Human Induced Pluripotent Stem Cell-Derived Engineered Heart Tissue as a Sensitive Test System for QT Prolongation and Arrhythmic Triggers
Summary
EHT from hiPSC-CMs shows a lower repolarization reserve than human LV working myocardium and could thereby serve as a sensitive and specific human-based model for repolarization studies and arrhythmia, similar to Purkinje fibers. In both human LV and EHT, IKs only contributed to repolarization under adrenergic stimulation. © 2018 American Heart Association, Inc.
