Effect of ISO on Ca²⁺ transient decline in NOS1^−/− vs WT myocytes. A) Summary data (mean±sem) of the effects of ISO on Ca²⁺ transient decline normalized to 3mM [Ca²⁺]_o in WT (clear bars) and NOS1^−/− (black bars) myocytes. B) Summary data (mean±sem) of the effects of ISO on Ca²⁺ transient decline time intervals normalized to 3mM [Ca²⁺]_o in WT (clear bars) and NOS1^−/− (black bars) myocytes. C) Summary data (mean±sem) of the effects of maximum 3mM [Ca²⁺]_o (left) and ISO (right) on Ca²⁺ transient RT₅₀ normalized to 1mM [Ca²⁺]_o in WT (clear bars) and NOS1^−/− (black bars) myocytes. * P<0.05 vs corresponding WT.
