Keiichi Fukuda (2012) studied Long QT syndrome. Patient-derived iPS cell cardiomyocytes vs. Healthy control iPS cell cardiomyocytes was evaluated on Field potential duration (FPD) and electrophysiological response to ion channel blockers. Patient-derived iPS cell cardiomyocytes successfully recapitulated the pathological features of Long QT syndrome, demonstrating prolonged field potential duration and disease-specific drug responses.
