针刺内关穴时有感传者和无感传者针刺效应的时间差异

本文对针刺内关时有感传者和无感传者心电图 ST 段和 T波变化的时间差异进行了观察。针刺时间15分钟到30分钟,部分患者观察90分钟。结果表明:针刺15分钟时,有感传者的心电图改善显著,而无感传者的心电图没有明显的变化,组间差异显著。针刺30分钟时,有感传者和无感传者的心电图都进一步改善。无感传者心电图改善的程度也有了显著意义,两组之间的差异不再显著。从部分患者针刺90分钟连续记录的动态心电图看到,有感传组的针效比无感传组好,出现显效的时间也比无感传组早。提示循经感传可能加快针刺对相应脏腑功能调节的过程。

THE DIFFERENCE IN THE TIME FOR THE APPEARANCE OF ACUPUNCTURE EFFECTS BETWEEN THE SUBJECTS WITH AND WITHOUT PSM DURING ACUPUNCTURE OF NEIGUAN

It has been reported thap ECG of the patients of coronary heart disease withPSM got marked Improvement when Neiguan(PC6)was punctured,in comparisonwith the patients without propagated sensation along meridians(PSM).Thedifference between the two was significant.However some others reported thatthe acupuncture effects between the two had no striking difference.Authorsdetected that during acupuncture of Neiguan the change of ECG of the patientsshowed dynamic character and some patients without PSM were also marked asthe duration of acupuncture was prolonged.For this reason,this paper wasaimed to observe whethe any difference appeared in the development of acupu-ncture effects between the patients with and without PSM.One hundred and seventy cases of patients with coronary heart disease wereobserved,of which 86 were male and 84 female,aged 35-83 years.Varying de-gree of PSM appeared in 80 of them,but not in the remaining 90.ECG wasrecorded with polygraph(model SJ-42)before acupuncture.Then the Neiguanacupoint of the left forearm was punctured by slow twisting for 5 minutes andthe feature of PSM was carefully observed.Another recording of ECG was ta-ken after retaining needle for 10 minutes:Retaining needle lasted for 30 minutes in a part of the patients and the needle was manipulated every 16 minules inorder to keep the needling sensation.The signals of ECG were added 10 timesby addscope(model ATAC-250),the voltage of ST segment and T wave of ECGwere measured and processed statistically.ECG of a part of the patients wererecorded continuously in a period of 90 minutes.The results of every 15 minuteswere processed and compared.The results of 254 times of obervation showed that the difference in thedegree of improvement of ST segment and T wave of ECG was significant(P<0.05)between the patients with and without PSM after acupuncturing Neiguanfor 15 minutes.However,after acupuncturing for 30 minutes,the ST segme-nt and T wave of ECG were further improved in both groups.The change ofECG in the patients without PSM was also remarkable,and thus,the differencebetween the two groups was no longer significant(P>0.05).From the resultsof acupuncture of Neiguan for 60 minutes it could be found that the acupunctu-re effect of the patients with PSM was better than that of without PSM,andthe appearance of the effect was also earlier in the former,in whom the acu-puncture effect had already become very marked in the initial 15 minutes afteracupuncture.The above results indicated that PSM was able to promote theregulation of the functional activities of the visceral organs durnig acupuncture.
