20 cases of chronic coronary ischaemia and focal cardiomyositis complicated with cholecystitis were treated by electric acupuncture of Neiguan points with pressure block. While the corresponding effects of the acupuncture on ECG changes were observed daily or every two days under fasting as well as 2 hours after meal. Administration of medicines was suspended on the day of observation. The weight of pressure applied for blocking was 500-600 gm/cm{2}. A control ECG was made before acupuncture and a blank ECG was also made in the day free from needling.
Being processed statistically, the results showed ECG effect of electrical stimulation of Neiguan can be blocked by pressure. The ratio of the mean gain of T-wave, with and without pressure, showed a marked difference, and so did the blank and needling (P<0.01 and P<0.05 respectively). T-wave changes usually appeared an hour after electrical needling. 7 of the 20 cases have propagated sensation along channels (PSC) of various length. All of the PSC were blocked by pressure. Those who had no PSC also had ECG effect after electrical needling. All the patients, either with presence of PSC or not, showed weakening of ECG effects produced by needling when pressure had been given. The results suggest that PSC is not essential for mechanical blockage of visceral adjustment of acupuncture.
