It was known in the ancient Chinese Medical literature that heart & chest diseases could be cured by needling on Neiguan point. In order to investigate further the specificity of different acupuncture points, we have applied noninvasive method to evaluate the cardiac function of coronary patients who received acupuncture on different points as a method of treatment. The II lead of ECG, apexcardiogram, carotid pulse wave and phonocardiogram were recorded both before & after acupuncture, and the following observations were made.
1. Electro-mechanical contraction time (Q-A[2])
2. Mechanical contraction time (MST)
3. Preejection period (PEP)
4. Left ventricular ejection time (LVET)
5. Isovolumetric contraction time (ICT)
6. PEP/LVET
7. LVET/ICT
8. A% Percentage of vertical amplitude of the beginning of A-wave in apexcardiogram over OE
9. OB% Percentage of vertical amplitude of B (B point is indicated as the first peak after the incisura of the descending limb of contracting wave) over OE
10. Vertical amplitude of apexcardiogram (OE)
A total of 32 patients with definite diagnosis of coronary heart disease were examined, most of them were those with old myocardial infarcts.
After the control records were made and the position of points were carefully selected, all the needlings were performed by one appointed doctor. Manual twisting of needles continued for 2 minutes after the needling sensation was first felt by the patient. After that, while the needles were still in place, the second records were made and the third records were made 15 minutes later just after withdrawning of needles. Each patient was examined twice, at an interval of 2 weeks. For the first needling, either Neiguan or Juegu was taken at random, and for the second, the other one was used.
The results were treated statistically. It was shown that the left ventricular function was improved both after needling Neiguan and Juegu for 2 minutes, as we could see that LVET and Q-A[2] etc. were definitely lengthened. We selected Juegu as a control point on the assumption that it belongs to the Gall-Bladder Channel of Foot-Shaoyang and is not concerned with the heart and chest. However in our data, it seemed to possess the same function as Neiguan, therefore as a preliminary conclusion, we could hardly refer Neiguan as the sole specific point for the coronary heart disease.
