针刺诱发感传对冠心病心绞痛病人的心脏收缩间期的影响

<正> 针刺对冠心病心绞痛病人已有明确的疗效,并能改善左心功能状态,为了进一步探讨针刺感传气至病所与疗效有否关系,我们采用心电图、心音图,颈动脉搏波图和心尖搏动图(ACG)同步记录,分析心脏收缩间期,了解针刺感传的敏感度不同和无感传对冠心病人的疗效有否差异,现将观察结果报道如下:

EFFECTS OF TOE PSC INDUCRD BY ACUPUNCTURE ON THE CARDIAC DIASTOLIC AND SYSTOLIC INTERVALS OF PATIENTS WITH ANGINA PECTORIS

The purpose of this study was to approach the relation between the PSC induced by acupuncture and the therapeutic effect of angina pectoris of coronary heart disease. The non-invasive methods, such as ECG, PCG, ACG and carotid pulsilogram were recorded synchronously to analyse the cardiac diastolic and systolic intervals. Patients were selected according to the criteria of diagnosis at the National Conference for Coronary Heart Disease held in 1974, and 123 cases, 68 male and 55 female, aged 33 to 75 years, with typical clinical symptoms and recent different changes of the ST-T wave in electrocar- diograms were studied. The patients were divided into three groups, one group (48 cases) indicated the acupuncture sensation being at the location of a point: in another group (43 cases) acupuncture sensation was propagated along the pericardium channel over the elbow joint, and in the 3rd group (32 cases) it was propagated to the chest over the shoulder reaching the affected area. Neiguan was needled bilaterally. In the same way, three records were made before acupuncture, re- taining for 15 min and immediately after withdrawal of needles during the period of observation. Acupuncture could slow down the heart rate markedly in 123 patients suffering from angina pectoris, significantly prolong QA, MS and SF, and definitely shorten PEP and decrease PEP/LVET, indicating that acupuncture may improve the function of the left ventricle of the pa- tient. ICT was significantly shortened, LVET prolonged, and LVET/ICT increased, indicating that the force of myocardial contraction was stron- ger after acupuncture. The decrease in A wave per cent in ACG indica- tes that the left ventricular end-diastolic pressure was decreased by acupuncture. The difference of the main parameters between these groups showed no statistical significance. This experiment demonstrated that the main parameters of the car- diac systolic interval of the patients with angina pectoris were improved and some good results obtained. However, there was no statistical signi- ficance among these groups, ie, PSC induced by acupuncture was not re- lated to the therapeutic effect.
