运动时,血流动力学的正常反应是心率加快,收缩压升高;而收缩压下降则常见于严重冠心病和急性缺血性左心功能不全者.本文旨在阐明运动试验时收缩压下降与冠状动脉造影结果之间的关系,并试图确定这些患者经内、外科治疗后,其血压下降反应的重现性以及远期预后.方法:436例患者,按标准Bruce方案进行分级踏车运动试验和冠状动脉造影检查.运动试验时描记12导联心电图,并测量上臂血压.当观察到收缩压下降时,半分钟内重复测量一次,以证实之.凡二次测量间收缩压下降达10毫米汞柱者,则停止运
Exercise, hemodynamic normal response is heart rate, systolic blood pressure increased; and systolic blood pressure drop is common in patients with severe coronary heart disease and acute ischemic heart failure.This paper aims to clarify the exercise test systolic blood pressure drop And coronary angiography and attempted to determine the reproducibility of these blood pressure response and long-term prognosis after internal and surgical treatment in these patients.Methods: 436 patients underwent standard treadmill exercise with Bruce regimen Test and coronary angiography. Exercise test tracing the 12-lead ECG, and measurement of upper arm blood pressure when systolic blood pressure is observed to decline, within half a minute repeated measurements to confirm it. Where the systolic blood pressure decreased between the two measurements of 10 MmHg, then stop shipping
