心电图ST-T改变研究

The research of ECG ST-T changing

目的 :研究心电图持续ST段下移与T波倒置的临床意义。方法 :选取心电图持续全导联ST段下移与T波倒置患者 30例 ,观察症状、体征、心电图、超声心动图、胸部正位片 ,共随防观察 5年。结果 :最后诊断肥厚性心肌病 17例 (5 6 .7% )、扩张性心肌病 4例 (13.3% )、心包炎 2例 (6 .7% )、糖尿病 3例 (10 .0 % )、原因不明者 4例 (13.3% )。结论 :左室肥厚是引起持续ST段下移与T波倒置的主要原因。患者预后与T波倒置深度无关 ,而主要取决于基础疾病的发展、恶性状态及伴发心律失常的情况。

Objective: To research the clinical significance by lasting ECG ST segment depression and T wave inversion.Methods: Thirty patients were followed for 5 years and symptoms,ECG,UCG,chest X-ray.Results: Of 30 patients,the final diagnosis was 17(56.7%)with hypertrophic cardiomyopathy,4(13.3%)with dilated cardiomyopathy,2(6.7%) with pericarditis,3(10.0%) with diabetesMellitus,and 4(13.3%) with unknown reason.Conclusion: The results Showed that left ventricular hypertrophy was the major cause of Inducing lasting ST segment depression and T wave inversion.Prognosis does not depend on the depth of T wave inversionbut mainly on the primary disease, and concomitant arrhythmias.
