Figure 2.

Heart rate (a), cardiac output (b), left ventricular stroke work (c), and mean arterial pressure (d) expressed as a consequence of cooling to 28°C and rewarming in animals receiving saline infusion (n = 7), or continuous infusion of (0.125 μg/min), and intermittent infusion of Epi (1.25 μg/min) during cooling to 28°C (n = 7). Before rewarming, infusions were terminated. Values are expressed as mean ± SEM. ⁺P < 0.05 compared with saline group, †P < 0.05 comparisons within Epi group at each temperature, and ‡P < 0.05 compared with prehypothermic value in saline group.
