the myocardial energetics correlation was also linear ( mean r = 0.939 ) and demonstrated an increased oxygen utilization characteristic of the higher inotropic state produced by calcium chloride infusion ( 0.047 +/- 0.003 versus 0.070 +/- 0.008 ml oxygen/beat/100 gm left ventricular weight , p = 0.008 ) .
