用Mx3型脉象仪描记68例冠心病患者(内有36例急性心肌梗塞患者)桡动脉脉象;用QFM1000型多普勒超声血流仪检测了其中20例的颈动脉桡动脉的血流量,流速、管径、搏动范围。计算得出零压周围阻力,血管容积弹性模数。与20例同年龄、除患有动脉硬化外,无其他心脑血管疾患者相对照,结果表明,慢性冠状动脉供血不足的患者与对照组比较,颈动脉血流量减少较桡动脉明显,而颈动脉、桡动脉零压周围阻力均增加,似表明这种改变是心源性的。急性心肌梗塞患者的脉象图改变主要是主波幅降低及全曲线总面积减少。
Sixty-eight patients with coronary heart disease (36 patients with acute myocardial infarction) had radial artery pulse recording with Mx3 pulse-shape instrument. The blood flow velocity and velocity of carotid artery radial artery of 20 patients were detected by QFM1000 Doppler ultrasonography. , Diameter, pulsation range. The calculated resistance around the zero pressure, vascular volume elastic modulus. Compared with 20 patients of the same age, except those with atherosclerosis, no other patients with cardiovascular and cerebrovascular diseases, the results showed that patients with chronic coronary artery insufficiency compared with the control group, carotid artery blood flow decreased more than the radial artery, and neck Artery, radial artery pressure around the increase in resistance, it seems that this change is cardiogenic. The change of pulse pattern in patients with acute myocardial infarction is mainly the decrease of the main amplitude and the decrease of the total area of the whole curve.
