days before labeling a patient hypertensive.2.Much lower in infants and children.3.BP equals flow(CO)times resistance,so whatever the causes are,they must lead to increase total peripheral resistance(TPR)by inducing vasoconstriction or to increase cardiac output(CO).,高血压(Hypertension),2、分类(Classification)：原发高血压(Primary/Essential)继发高血压（症状性高血压Secondary）:5%3、意义：高危因素：动脉粥样硬化、冠心病重要原因：心力衰竭,hl:Secondary is associated with bilateral parenchymal disease or
