Objective: To investigate the effect of Fuzi Lizhong decoction at different doses on heart rate and myocardial enzyme in rats with hemorrhagic hypotension. Methods: Rats were randomly divided into normal group,model group,and high-,middle-,and low-dose Fuzi Lizhong decoction groups,with 10 rats in each group. All rats except those in the normal group were used to establish a rat model of hemorrhagic hypotension.
