title: The effects of electroacupuncture at the heart meridian on myocardial contractile function in rabbits with myocardial ischemia.
abstract: Acute myocardial ischemia was induced by intravenous injection of pituitrin, and electroacupuncture (EA) was applied at the Heart and Lung Meridians (HM and LM), 3 points on each meridian. The changes in the left intraventricular pressure (LVP), the maximum rise rate of intraventricular pressure (LVP dp/dtmax), the area of cardiac force loop (ACFL), and the maximum shortening velocity of myocardial contractile element (Vmax) were observed. As a result, there were significant differences in the improvement of LVP, LVP dp/dtmax, ACFL and Vmax between EA at HM and LM. The regulatory action of EA at HM on the myocardial contractile function was significantly better than that of EA at LM, indicating that HM has a close relationship with the myocardial contractile function.
