倒置T波正常化与冠心病相关性研究

Relationship between inverted T wave normalization and coronary heart disease

目的探讨24h动态心电图检查发现倒置T波出现正常化(TWN)改变与冠心病(CHD)相关性,其对心肌缺血的诊断价值及临床意义。方法回顾性分析动态心电图检查结果,有TWN改变患者75例,全部患者行冠状动脉造影(CAG)检查明确诊断,部分患者经皮冠状动脉介入术(PCI)。结果 CAG阳性70例,阴性5例。结论 24h动态心电图检查发现TWN改变与CHD显著相关,可以作为心肌缺血的一个诊断指标,TWN可在PCI术后早期出现。

Objective To observe the relationship and clinical significance of the inverted T wave normalization（TWN） during 24 hour Ambulatory electrocardiogram（Holter） and coronary heart disease（CHD）.Methods A retrospective analysis 75 cases of patients with TWN.All patients underwent coronary angiography（CAG）,some patients undergoing percutaneous coronary intervention.Results The diagnosed positive CHD of 70 cases,negative 5.Conclusions There is significant correlation inverted TWN and CHD,can be used as a diagnostic marker of myocardial ischemia.which can be advanced in early after PCI.
