Fig. 2. Rate–pressure product (RPP) and electrocardiogram during recovery. QRS duration (  A ) and RPP (  B ) are shown during the recovery from bupivacaine-induced asystole (mean ± SEM; n = 5 for all values, except QRS duration in the saline group, where n = 4). # Significant differences with the mean value of the saline group. * Significant differences with epinephrine-treated animals.  One symbol ,  P < 0.05;  two symbols ,  P < 0.01;  three symbols ,  P < 0.001. EPI = epinephrine-treated group; L = lipid-treated group; SALINE = control group.
