Prolongation of Action Potential in Human Atrial iPSC Cardiomyocytes
By detecting the mechanics of disease conditions in muscles, Nautilus enables high-throughput screening and discovery applications. Here, Nautilus accurately detected conduction arrhythmias in human atrial hiPSC-CMs by measuring the prolongation and triangulation of Action Potential (AP) in response to E-4031 compound.

Positive Inotropic & Chronotropic Responses to Isoproterenol
Intracellular Calcium optical mapping of iPSC-cardiomyocytes using Nautilus instrument provides predictive response to Isoproterenol.
Enables Detection of Dose Response Toxicity
Voltage Optical Mapping of iPSC-CMs: Pentamidine, an antiprotozoal agent, has been traditionally known to cause QT prolongation and arrhythmias. Here, we are showing the dose response cardiotoxicity of Pentamidine in human atrial iPSC cardiomyocytes using the Nautilus optical mapping instrument.
