Final answer:
Hemoglobin level is not a determinant of myocardial oxygen supply.
Step-by-step explanation:
Out of the options given, Hemoglobin level is NOT a determinant of myocardial oxygen supply.
Myocardial oxygen supply is primarily determined by factors such as coronary blood flow, blood oxygen saturation, and diastolic time.
For example, if there is a decrease in coronary blood flow or blood oxygen saturation, the myocardial oxygen supply may be compromised, leading to ischemia.
Hence, Hemoglobin level is not a determinant of myocardial oxygen supply.
