心电向量图T环异常对冠心病的诊断88例分析

Abnormal T-ring of Vectocardiogram to Diagnosing Coronary Heart Disease:Report of 88 Cases

目的 探讨心电向量图T环改变对冠心病的诊断价值。方法 使用北京中信公司的心电工作站心电系统 ,对 88例冠心病病人进行心电向量描记 ,并用 90例正常人为对照组 ,对T环进行定量分析。结果 正常组 :心电向量图以QRS -T夹角增大多见 ,T环方位异常较少见。冠心病组 :心电向量图T环异常符合心肌缺血的诊断 ,与正常组比较各项指标差异均有显著意义 (P <0 .0 5 )。结论 心电向量图T环对冠心病的诊断较敏感 ,在临床诊断冠心病中具有较高的使用价值。

Objective To evaluate abnormal T-ring of vectocardiogram to diagnose coronary heart disease.Methods Analyse the abnormal T-ring of 88 cases with coronary heart disease and of 90healthy cases.Results The abnormal T-ring of coronary heart disease was more often than that the healthy group, the difference was significant (P<0.05).Conclusion Abnormal T-ring of vectocardiogram is of great value to the diagnosis of coronary heart disease.
