These data include field potential recordings from human pluripotent stem cells-derived cardiomyocytes. The data are recorded by Cardio2D software and analyzed offline by Cardio2D+. The characteristics of the field potentials such as field potential amplitude, field potential duration and beating duration as well as beating frequency, were obtained. Based on these characteristics, the field potentials were categorized to normal or arrhythmic by two electrophysiology experts.
