心电图Tv_1>Tv_(5,6)对冠心病的诊断价值

Diagnosis Value Evaluated by Tv_1>Tv_(5,6) in Coronary Artery Disesse

目的 探讨心电图 (ECG) v1 ,5,6 导联 T波的特征 T v1 >T v5,6 在冠心病的诊断及预后评价中的作用。方法 分析 2 2 5例因胸部不适而接受冠状动脉造影 (CAG)患者的心电图 T v1 >T v5,6 阳性率在 CAG阳性及阴性组中的差异 ,以及随访观察 CAG阳性患者中冠状动脉 (简称冠脉 )事件发生率。结果 T v1 >T v5,6 阳性率在 CAG阳性组和阴性组中分别为48.8% ,3 3 .3 % ,两者间差异显著 (P<0 .0 1 ) ;在 CAG阳性组和阴性组中 ,有无高血压不影响 T v1 >T v5,6 的阳性率 ;CAG阳性患者中 ,有 T v1 >T v5,6 阳性患者冠脉事件发生率高于 T v1 >T v5,6 阴性患者。结论 对于胸部不适的患者 ,心电图 T v1>T v5,6 阳性可提示冠脉存在病变 ,并可预示在 CAG阳性患者中 ,有 T v1 >T v5,6

Objective To investigate the T wave characters of leads v 1, v 5, v 6 in patients with suspected to suffer from coonary artery disease(CAD), T v 1 >T v 5,6 was analysed Methods From August 2000 to February 2002, 214 of 225 patients which were suffered from chest pain or uncomfortableness, excluded acute myocardial infarction, myocardiopathy and hypertensive heart disease, were undergone coronary angiography T v 1 >T v 5,6 were analyzed between CAG positive group and CAG passive group, between hypertension and non hypertension group Cardiovascular events(including cardiac death, acute myocardial infarction and revascularization)was evaluated in 93 patients with CAG positive between T v 1 >T v 5,6 positive group and T v 1 > T v 5,6 passive group at 6 month follow up Results The rate of T v 1 >T v 5,6 in CAG positive group and CAG passive group were 48.8%, 33.3%, respectively The discrepancy was significant Hypertension didn't influence on the rate of T v 1 >T v 5,6 positive in CAG positive group or CAG passive group At 6 month follow up, morbidity rates of cardiac death, acute myocardial infarction and revascularization were significantly higher in T v 1 >T v 5,6 positive patients(13.5%, 20.0% respectively)vs T v 1 >T v 5,6 passive patients(7.3%, 12.2%, 17.0% respectively)with CAG positive Conclusion In CAG positive patients, there were significant lesions of coronary artery with T v 1 >T v 5,6 positive, and T v 1 >T v 5,6 positive was an implication of higher cardiovascular events
