Figure 3 Comparison of deltaST max and sigmaST during the second inflation among control (first inflation of the PC60 and PC180 groups), PC60, PC180, NC and ISDN groups. Significant decreases in ST elevation (deltaST max and sigmaST) in the PC180 group at every time point, and in the NC group at the 30 s and 60 s points after inflation, were observed.
