Summary
It is observed that at voltage-clamped membrane potentials of +60 mV in perforated whole cell studies, the normalized outward current densities in fetal myocytes were >30% higher than in those of the adult (P < 0.05) and that these were predominantly due to iberiotoxin-sensitive currents from BKCa channels.
