O2 consumption by the myocardium is in mL/100 g/min is:

Basal O2 consumption by the myocardium is about 2 mL/100 g/min. O2 consumption by the beating hea is about 9 mL/100 g/min at rest. O2 consumption by the hea is determined primarily by the intramyocardial tension, the contractile state of the myocardium, and the hea rate. Ref: Barrett K.E., Barman S.M., Boitano S., Brooks H.L.
