A total of 30 students scoring between 12 and 20 on the Test Anxiety Scale who had been exhibiting an anxious state 〉 24 hours, and 30 normal control students were recruited. Indices of heart rate variability were recorded using an Actiheart electrocardiogram recorder at 10 minutes before auricular pressing, in the first half of stimulation and in the second half of stimulation. The results revealed that the standard deviation of all normal to normal intervals and the root mean square of standard deviation of normal to normal intervals were significantly increased after stimulation. The heart rate variability triangular index, very-low-frequency power, low-frequency power, and the ratio of low-frequency to high-frequency power were increased to different degrees after stimulation. Compared with normal controls, the root mean square of standard deviation of normal to normal intervals was significantly increased in anxious students following auricular pressing. These results indicated that auricular pressing can elevate heart rate variability, especially the root mean square of standard deviation of normal to normal intervals in students with pre-exam anxiety. 展开更多

Objective: To evaluate angiographical diameter and pressure changes of coronary artery and heart rate in patients with coronary heart disease (CHD) or suspected CHD immediately after electric pulse stimulation of Zhiyang point. Methods: Twenty-four patients including 21 males and 3 females with an average age of 48. 7 years were enrolled. Parameters of electric pulse stimulation were as follows: the positive pulse range was 440 V, the negative pulse range 160 V, the cycle 8 ms, frequency 125 Hz, the positive pulse width was 0. 8 ms,the negative 0. 4 ms, and the output voltage 9 V. Coronary arteriography was performed by using Judkins technique, and intracoronary pressure with heart rate and any response of patients to the stimulation were recorded preand post-stimulation for 90 seconds. The relative diameter of left main coronary artery (LMCA ), left anterior descending artery (LAD ), left circumflex coronary artery (LCx), and right coronary artery (RCA) before and after the stimulation was measured in the same magnification and their results with recordings of intracoronary pressure and heart rate was analyzed. Results: A mild dilation effect was observed in all coronary arteries with an average dilation of 8. 3 % (6. 3 % - 15 % ) in LMCA, 7. 7% (5% - 11. 8%) in LAD, 8.5% (6. 7% - 11. 1% ) in LCx, and 9. 1% (6.1 % - 13. 3 % ) in RCA. No significant difference was found in the change of the diameter of LMCA, LAD, LCx and RCA before and after the stimulation. No significant change of intracoronary pressure was shown in three patients, an increase of intracoronary systolic and diastolic pressure by 36 % and 13 % was identified in one, and a decrease by 21 % and 31 % in another patient. Heart rate was decreased by 2. 3 % in those five patients. Conclusion:Electric pulse stimulation of Zhiyang point can immediately produce mild dilation effect on coronary arteries, slight decrease on the heart rate, and different effects was produced in intracoronary pressure.Original article on CJIM(Chin) 1998; 18(6): 330 展开更多
