<prompt> O2 consumption by the myocardium is in mL100 gmin is:210100150  <response>: Basal O2 consumption by the myocardium is about 2 mL100 gmin. O2 consumption by the beating hea is about 9 mL100 gmin at rest. O2 consumption by the hea is determined primarily by the intramyocardial tension, the contractile state of the myocardium, and the hea rate.
