Abstract
At the beginning of a 10 sec arterial haemorrhage, vascular elasticity induces an increase of mean diastolic coronary resistance. Then, the increase is counteracted by the relaxation of the vascular musculature, which causes a coronary hyperaemia when, after the haemorrhage is arrested, the vascular wall is stretched by a sudden though slight increase of blood pressure.
摘要
在10秒动脉出血开始时，血管弹性导致平均舒张期冠状动脉阻力增加。然后，这种增加被血管肌肉组织的舒张所抵消，当出血停止后，血管壁因血压突然轻微升高而被拉伸，从而导致冠状动脉充血。
