AP biomarkers measured in control and mutant hiPSC-CMs paced at 60 bpm by Bellin et al. [4]. AP biomarkers are expressed as mean ± SD. APA: AP amplitude. APD₅₀ and APD₉₀: AP duration at 50% and 90% of repolarization, respectively. dV/dt_max: maximum upstroke velocity. MDP: maximum diastolic potential. Peak: peak voltage. Rate: stimulation frequency.
