Coronary blood flow

 

Some heart-specific figures:

  • 300g by weight
  • 5% of cardiac output
  • 10% of total basal oxygen consumption
    [KB2:p52]
  • ~12% of basal oxygen consumption
    [WG21:p615]

 

Coronary blood flow

= 5% of cardiac output

= 250mL/min

Thus, O2 flux = 50mL O2/min delivered

Coronary sinus

90% of coronary bloods return via coronary sinus

PO2 of coronary sinus blood = 20mmHg
