Figure 8.

Recovery (over 1 h) of left ventricular pressure, blood pressure, V̇O₂ and lactate concentrations in the nine animals exposed to lethal dose of CN. The group that received CN is displayed in red, while the group of rats that received 20 mg/kg MB and CN is shown in blue. All variables were back to baseline within 20 min in the group treated with MB except for lactate, which concentration remains elevated during all the recovery period. Note that one of the rats in the treated group had lower recovery values for VO2 and dP/dt than the rest of the group up to 15 minutes, accounting for a larger standard deviation during this period.
