为了提高运动试验的诊断价值,作者分析下列附加变数在解释运动耐量试验中的重要性,以补充传统的ST段标准:(1)运动引起的心绞痛样胸痛;(2)运动高峰时的心率—血压乘积(双乘积);(3)运动后ST段压低的持续时间;和(4)ST段压低深度。方法:237例因胸痛综合征而进行心脏导管检
To improve the diagnostic value of exercise testing, the authors analyze the importance of the following additional variables in interpreting exercise tolerance tests to supplement the traditional ST segment criteria: (1) exercise-induced angina pectoris; (2) heart rate at peak exercise - Blood pressure product (double product); (3) Duration of ST segment depression after exercise; and (4) Depth of ST depression. Methods: 237 cases of cardiac catheterization due to chest pain syndrome
