Myocardial parameter in quantum resonance magnetic analyzer:
Myocardial Blood Demand: The blood demand per minute of coronary artery perfusion of heart.
Myocardial Blood Perfusion Volume: The actual blood demand per minute of coronary artery perfusion of heart.
Myocardial Oxygen Consumption: The milliliter value of oxygen consumption of heart per minute.
Influence Factors: Three aspects
(1) Heart rate: the heart rate is fast, and the HOV is great. (2)
(2) Myocardial contractility: the cardiac contractility is strong, and the HOV is great.
(3) Myocardial contraction time: the longer the contraction time is, the greater the HOV is. Thus, low oxygen consumption and high cardiac work are the best state.
