目的:探讨针刺内关与郄门穴对冠心病患者每博心输出量及左心室排血的峰值流速的影响.方法:60例冠心病患者分为内关组和郄门组,分别在运针3 min后和留针20min后测试每博心输出量,左心室排血的峰值流速.再与针刺前得测试结果相比较.结果:46例患者针刺3 min后Q值和VP值较针刺前上升.留针20min后,34例患者Q值和VP值全部上升.结论:针刺内关和郄门可增强左心室壁的收缩能力,使心脏的每博输出量增加,改善冠心病患者的心肌缺血状态.,Purpose: This study is to investigate the influence of acupuncture at acupoints Neiguan (PC 6) and Ximen (PC 4) on the stroke volume and the flow rate of peak value of left ventricle ejection in the patients with coronary heart disease. Methods: 60 cases of coronary heart disease were divided into acupoint Neiguan (PC 6) group and acupoint Ximen (PC 4) group, and the stroke volume and the flow rate of peak value of left ventricle ejection were detected 3 min after manipulating needles and 20 min after retaining needles respectively, then were compared with those before acupuncture. Results: 3 min after manipulating needles, the stroke volume and the flow rate of peak value of left ventricle ejection were enhanced in 46 cases, and 20 min after retaining needles, both the stroke volume and the flow rate of peak value of left ventricle ejection were all enhanced in 34 cases. Conclusion: Puncturing acupoints Neiguan (PC 6) and Ximen (PC 4) could enhance the contractility of left ventricle wall, increase the stroke volume of the heart and improve the myocardial ischemia in the patients with coronary heart disease
