Effects of 3 mM [Ca²⁺]_i and ISO on Ca²⁺ transient decline with matched Ca²⁺ transient amplitudes in NOS1^−/− myocytes. A) Representative trace of matched [Ca²⁺]_i amplitudes with 3 mM [Ca²⁺]_o (black) or 10⁻⁶ M ISO (gray). B) Summary data (mean±sem) of matched Ca²⁺ transient amplitude with 3mM [Ca²⁺]_o (black) or ISO (gray). C) Summary data (mean±sem) of Ca²⁺ transient decline with 3mM [Ca²⁺]_o (black) or ISO (gray). (D) Summary data (mean±sem) of Ca²⁺ transient decline time intervals with 3mM [Ca²⁺]_o or ISO. * P<0.05 vs corresponding 3 mM [Ca²⁺]_o.
