Ionic currents responsible for low amplitude, long duration Jspon-induced EAD upstroke. Three calculations of the average rate of change of membrane ionic currents, İi (μA/(cm2 × s) ), over a 35 ms interval: immediately before the EAD upstroke (İi,EAD), during the same phase of repolarization of an AP without an EAD (İi, noEAD), and the difference between the first two cases (İi,EAD − İi, noEAD).
