Pituitrin 20μ/kg is injected in abdominal cavity

and then the model of myocardial ischemia is established. The RRI and TV are markedly reduced in the group of moxa Heart Merldian. After moxa it

the improving effects of HRV may be maintained beyond halfan hour. The RRI and TV are slightly reduced within 5

10 minutes in the group of moxa Lung Meridian. After moxa it

the improving effectsof HRV is unclear. The results indicate that the improving roles of HRV in the group of moxa HeartMeridian is much better than the group of moxa Lung Merjdian or model. There is relative specificityof moxa Heaft Meridian
