Minimum and maximum experimental values for the 9 AP biomarkers recorded in human cardiac Purkinje cells at multiple BCL: 400 ms (n = 7), 500 ms (n = 7), 700 ms (n = 9), 1000 (n = 17), 1500 ms (n = 9), 2000 ms (n = 7), 3000 (n = 8), 5000 ms (n = 8).

BCL: Basic cycle length; dV/dt_MAX: maximum upstroke velocity; APD_x: AP duration at X% of repolarisation; APA: action potential amplitude; TOP: membrane potential before depolarisation; EOP: membrane potential at the end of repolarisation.
