EFFECT OF ELECTROACUPUNCTURE OF THE HEART MERIDIAN ACUPOINTS ON ISCHEMIC CARDICA FUNCTION IN THE RABBIT

Subjective:To observe the effect of electroacupuncture(EA) of acupoints of the Heart Meridian and Lung Meridian on ischemic cardiac systolic ability for analyzing the realtive specific relationship between the Heart Meridian and the heart.Methods:Acute myocardial ischemia(AMI) Was produced by intravenous infusion of pituitrin (40u 5% glucose injection 500 ml,60 drips/min)in the rabbit.Left intraventricular pressure(LVP),maximal rising velocity of LVP(dp/dt max),isovolumetric pressure(IP)and end-diastolic pressure(EDP)of the left cardiac ventricle were used as the indexes.Three points of Heart Meridian [HM,from“Shenmen“)HT7)to “lingdan“(HT4)] and the three points of Lung Meridian[LM,from“Taiyuan”(LU9)to“Lieque”(LU7)]were punctured with filiform needles and stimulated with hand-manipulation and electrically with ZYZ-1 EA Therapeutic Apparatus.30 rabbits anes-thetized with urethane(1g/kg) were randomly and evenly divided into control group,HM group and LM group.Results:The effects of EA of HM points were evidently superior to those of EA of LM points in promoting the recovery of both AMI-induced decrease of LVP and dp/dtmax,and AMI-induced increase of IP and EDP.Conclusion:Acupoints of Heart Meridian has a relatively specific connection with the heart in comparison with those of Lung Meridian;and the Heart Meridian is a functionalo whole.
