心尖球形综合征和ST段抬高型心肌梗死的T(p-e)/QT比值分析

T(p-e)/QT in Transient Left Ventricular Apical Ballooning Syndrome and Anterior ST Segment Elevation Myocardial Infarction

目的探讨心尖球形综合征和ST段抬高型心肌梗死的T(p-e)/QT比值的临床意义。方法对比分析18例诊断为心尖球形综合征患者和36例诊断为ST段抬高型心肌梗死患者的T(p-e)/QT。结果心尖球形综合征患者T(p-e)间期和T(p-e)/QT分别为(156.78±28.67)ms和(0.31±0.05),ST段抬高型心肌梗死患者分别为(123.34±37.45)ms和(0.23±0.04),差异均有统计学意义(P<0.001)。结论 T(p-e)/QT检测是一个有价值的非侵入性检测方法,可对鉴别心尖球形综合征和ST段抬高型心肌梗死提供帮助。

Objective The aim of our study is to evaluate the clinical significance of T（p-e） /QT in transient left ventricular apical ballooning syndrome（TLVABS） and anterior ST segment elevation myocardial infarction（STEMI）.Methods A total of 18 patients with TLVABS diagnosis and 36 age and sex matched patients with STEMI diagnosis were compared,with the STEMI patients enrolled as controls.Results T（p-e） and T（p-e） /QT in TLVABS patients（（156.78±28.67）ms and（0.31±0.05）） were significantly different from those in ST segment elevation myocardial infarction patients（（123.34±37.45）ms and（0.23±0.04））（P0.001）.Conclusion Our result suggests that the value of T（p-e） /QT can be a valueble noninvasive way for differential diagnosis of TLVABS and STEMI.
