Figure 3. (A) Coronary blood flow (CBF) [left anterior descending coronary artery], (B) peripheral blood flow (PBF) [femoral artery], (C) coronary vascular resistance (CVR), and (D) peripheral vascular resistance (PVR) in malignant hyperthermia-susceptible (MHS) (filled circles; n = 12) and non-MHS (nMHS) swine (open circles; n = 8) during baseline recordings (t = 0) and after 90 min of halothane exposure (1% inspired) in addition to succinylcholine (3 mg *symbol* kg sup -1 intravenously 15 min after the start of halothane exposure). Data are expressed as percentages of baseline values. Scales of the ordinates differ. *P < 0.05 versus baseline; triangles = P < 0.05 MHS versus nMHS.
