translate English to French: By lowering the holding potential to −30 from −80 mV, the time constants of both fast and slow components were increased to 740 and 4820 ms, respectively, suggesting that the recovery of Ca2+ channels from Ca2+-mediated inactivation is voltage dependent.
En diminuant ce potentiel à −30 mV, les constantes de temps des composantes rapides et lentes ont augmenté à 740 et 4820 ms respectivement, ce qui suggère que le rétablissement de l'activation des canaux Ca2+ est voltage-dépendant.
