心电遥测可动态地观察心电图改变,我院自1966年采用遥测技术作二级梯及亚极量平板运动试验。现将101例遥测运动试验结果与二级梯及平板运动试验的结果作比较分析,初步探讨遥测运动试验的方法、阳性标准及使用价值。病例选择 1.选择140例临床无器质性心脏病、心电图正常者,加做CM_5、CC_6导联,以观察其特异性。另选30例心电图示慢性冠状动脉供血不足者,加做CM_5、CC_5导联,以观察其反映异常ST—T的敏感性。 2.运动试验病例选自可疑冠心病人(有心前区痛、胸闷、高血脂者)74例,多年早搏或多次阵发性房颤者9例,另外18例因工作需要查体。在101例中除3例女性外其余均为男性。运动前血压不高于140/90,常规12个导联及CM_5、CC_5导联心电图正常者,先做二级梯
ECG telemetry can dynamically observe changes in ECG, our hospital since 1966 telemetry as a secondary ladder and sub-plate treadmill exercise test. Now 101 cases of telemetry exercise test results and the two ladder and treadmill exercise test results for comparative analysis of the telemetry exercise test methods, positive standards and value. Case selection 1. Select 140 cases of clinical non-structural heart disease, normal ECG, plus do CM_5, CC_6 lead to observe its specificity. Another 30 cases of ECG showed chronic coronary insufficiency, plus do CM_5, CC_5 lead, to observe its sensitivity to reflect the abnormal ST-T. 2. Exercise test cases were selected from suspected coronary heart disease patients (with precordial pain, chest tightness, hyperlipidemia) 74 cases, many years of premature beats or multiple episodes of paroxysmal atrial fibrillation in 9 cases, the other 18 cases due to work needs examination. In 101 cases, except for 3 women, the rest were male. Pre-exercise blood pressure is not higher than 140/90, conventional 12 leads and CM_5, CC_5 lead electrocardiogram normal, first to do a two ladder
