Figure 2

Peak maximum development of coronary perfusion pressure, coronary artery average peak blood flow velocity and amplitude spectrum area. a = Development of CPP in the combined group, (0.02 mg EPI/kg/dose and 0.03 mg EPI/kg/dose) compared to control group (NaCl) during the MCC-period (15 min). Significant difference between EPI-group compared to control group, * = p <0.05. b = Development of APV in the combined group, (0.02 mg EPI/kg/dose and 0.03 mg EPI/kg/dose) compared to control group (NaCl) during the MCC-period (15 min). Significant difference between EPI-group compared to control group, * = p <0.05. c = Development of AMSA in the combined group, (0.02 mg EPI/kg/dose and 0.03 mg EPI/kg/dose) compared to NaCl during the MCC-period (15 min). EPI = epinephrine, NaCl = saline, CPP = coronary perfusion pressure (mmHg), inj = injection number 1- 4, Peak 1 – 4 corresponding to injection 1 - 4, APV = average peak velocity (cm/s), AMSA = amplitude spectrum area (mV · Hz).
