| 目的 :通过血管造影观察脉冲电刺激至阳穴后冠状动脉 (冠脉 )直径、压力和心率的即刻变化。方法 :男 2 1例 ,女 3例 ,平均年龄 48 7岁 ,脉冲电刺激参数 :正脉冲幅度 44 0V ,负脉冲幅度 1 60V ,周期 8ms,频率 1 2 5Hz,正脉宽 0 8ms,负脉宽 0 4ms,输出电压 9V。刺激至阳穴 90s前后 ,采用Judkins法行冠脉造影并记录冠脉压力、心率及患者反应。以同一放大率直接测量刺激前后冠脉相对直径 ,比较其扩张程度、压力和心率变化。结果 :脉冲电刺激后即刻全部冠脉扩张 ,其中左冠脉主干平均扩张 8 3 % (6 3 %～ 1 5 % ) ,左前降支平均扩张 7 7% (5 %～ 1 1 8% ) ,左回旋支平均扩张 8 5 % (6 7%～ 1 1 1 % ) ,右冠脉平均扩张 9 1 % (6 1 %～1 3 3 % )。刺激前后冠脉扩张及各支之间扩张程度均无显著性差异。刺激后 3例冠脉压力无显著性差异 ,1例冠脉收缩压和舒张压分别升高 3 6%和 1 3 % ,1例分别降低 2 1 %和 3 1 %。该 5例心率平均减慢 2 3 %。结论 :脉冲电刺激至阳穴后即刻可轻度扩张冠脉 ,心率趋向减慢 ,但对冠脉压力影响不一。 |

| 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 (Du. 9) point. Methods: Twenty four patients including 21 males and 3 females with an average age of 48.7 years. Parameters of electric pulse stimulation were as follows: the positive pulse range was 440 V, the negative pulse range was 160 V, the cycle was 8 ms, frequency was 125 Hz, the positive pulse width was 0.8 ms, the negative was 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 pre and 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 and between them. No significant change of an 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. Conclusions: Electric pulse stimulation of Zhiyang point could immediately produce mild dilation effect on coronary arteries, slight decrease on the heart rate, and different effects was produced in intracoronary pressure. |
