我们在过去心包经循经感传时对心率影响工作的基础上进一步探讨心包经循经感传心阻抗图的变化

在感传过程中心率变化时心输出量、心脏指数等心功能指标有何影响。方法对象:皆为7～12岁经胸透、心电、听诊检查、心肺正常之儿童

男23例、女28例共51例分二组。 1.心包经有感传组:20例 2.心包经无感传组:31例步骤:有感传儿童静卧10～20分钟后用Eifty-one normal children ranging from 7-12 years old were studied. Among them propagated sensation (PS) was observed in 20 cases and no PS in 31 cases. When the left pericardium channel PS travels to the precardiac region. electrocardiogram

dz/dt max. impedance cardiogram and phonocar- diogram were recorded and the following obsevations were made Heart rate (HR) Stroke volume(SV) Cardiac index(CI) Cardiac output(CO) Shortening of the preejecton period(PEP) Left ventricular ejection time(LVET) PEP/LVET Q-Z dz/dt max. Heather index (HI) When the pericardium channel PS reached the precardium

HR

CO

CI

were all increased with statistical significance. In the group without PS

the HR alone was changed. According to the above results

it may be con- sidered that the pericardium channel is closely related to the heart. When pericardiun channel PS exists not only HR but also the cardiac function (CO

CI) increases. For the group without PS

no statistical significance was found in any of the indices.
