摘要
目的 观察急性下壁心肌梗死心前导联ST段压低与冠状动脉病变的关系。方法 对 38例急性下壁心肌梗死患者均常规行冠状动脉造影检查 ,根据常规心电图心前导联ST段压低≥ 1 0mm分为STV1～ 4 压低组 (17例 )与STV1～ 6压低组 (2 1例 ) ,比较心电图与冠状动脉造影之间的关系。结果 STV1～ 4 段压低是下壁ST段抬高的对应性改变(P <0 0 1) ,STV1～ 6段压低证实合并明显的前降支病变(P <0 0 1) ,其灵敏度、特异度、阳性预测值、阴性预测值分别为 86 %、88%、90 %、83%。结论 急性下壁心肌梗死心电图STV5V6压低是合并前降支病变证据。
Objective To investigate the value of electrocardiogram reciprocal ST segment depression during acute inferior myocardial infarction. Method Thirty eight patients (31 men and 7 women) were allocat ed into two groups based on the extent of precordial ST segment depression: widespread (V 1～6 ) ST depression and localised V 1～4 ST depression. Results ST segment depression in V 1～4 in purely a reciprocal phenomenon. Widespread(V 1～6 ) ST segment depression indicates a reciprocal phenomenon and disease of left anterior descending coronary artery. The sensitivity, specificity, and positive and negative predictive values in predicting disease in the left anterior descending coronary artery were 86%, 88%, 90%, 83%. Conclusion ST segment depression in leads V 5 and V 6 is an indicator of disease of left anterior descending coronary artery in acute inferior wall myocardial infarction.
