5. Vascular Elasticity:refers to the expansion extent of arterial vascular elasticity during systolic ejection.
Influence Factors: (1) The size of SV. The greater the SV is, the greater the FEK is. (2) Emptying rate. The faster the emptying rate is, the smaller the FEK is. (3) Bad vascular elasticity.
The SV is not low, the emptying rate is not fast, and the FEK is also small, so it is possible to determine the possibility of hardening of blood vessels. It should not determine the possibility by a single parameter. The increase of vascular elasticity is seen in the mildly elevated systolic blood pressure, the mildly reduced diastolic blood pressure, the mildly increased pulse press and slightly higher blood pressure. The decline is seen in mildly atherosclerosis, coronary heart diseases, blood stagnation type chest pain, Yang Qi deficiency type chest pain, etc.
6. Myocardial Blood Demand:The blood demand per minute of coronary artery perfusion of heart.
7. Myocardial Blood Perfusion Volume:The actual blood demand per minute of coronary artery perfusion of heart.
8. 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.
