Figure 3.

Opioid effects on ventricular arrhythmias during reperfusion. Shown is a comparison of ventricular arrhythmia scores during the first 45 min of working mode perfusion. Quantification of arrhythmias using a scoring system (scored every 9 min) showed a decrease in relative arrhythmia occurrence with Deltorphin D during the early periods of working mode perfusion compared to the cariporide group. While mean arrhythmia scores were lower in the Deltorphin D-treated hearts compared to controls during the first 9 min of working mode, this difference was not significant (P = 0.1). *P < 0.05 versus cariporide
