【摘要】 目的:探討心電圖U波倒置在急性冠脈綜合征(ACS)診斷中的應用。方法:選擇筆者所在醫院2015年1月-2016年12月收治的110例ACS患者為研究對象,按心電圖檢查結果有無U波倒置進行分組,其中51例U波倒置的患者為觀察組,59例無U波倒置的患者為對照組,比較兩組患者確診ACS后心律失常的發生情況。結果:觀察組的竇性心動過緩、非持續性室性心動過速、竇性心動過速患病率均高于對照組,差異有統計學意義(P<0.05)。觀察組冠脈病變兩支和三支的發生率明顯高于對照組,差異有統計學意義(P<0.05)。結論:心電圖U波倒置可以作為預測ACS患者后期病情嚴重程度的一項指標。

Application of U Wave Inversion of Electrocardiogram in the Diagnosis of Acute Coronary Syndrome/YANG Tao.//Chinese and Foreign Medical Research,2017,15(32):97-99
【Abstract】 Objective:To investigate the application of U wave inversion in the diagnosis of acute coronary syndrome(ACS).Method:110 cases of ACS patients in our hospital from January 2015 to December 2016 were selected as research objects,according to the ECG results with or without U wave inversion group,51 patients with U wave inversion as the observation group and 59 patients without U wave inversion as the control group.The differences of arrhythmia during follow-up between the two groups were observed.Result:Compared with the control group,the incidence of sinus bradycardia,non persistent ventricular tachycardia and sinus tachycardia were obviously higher in the observation group,the differences were statistically significant(P<0.05).Compared with the control group,the incidence of coronary artery disease in two and three branches were significantly higher in the observation group,the differences were statistically significant(P<0.05).Conclusion:The inversion of U wave in ECG can be used as an index to predict the severity of ACS .

急性冠脈綜合征(acute coronary syndrome,ACS)是指冠狀動脈內不穩定的粥樣斑塊破裂或糜爛引起血栓形成所導致的心臟急性缺血綜合征,可分為ST段抬高型心肌梗死(STEMI)、非ST段抬高型心肌梗死(NSTEMI)和不穩定性心絞痛(UA)。ACS患者往往后續易發生主要不良心血管事件(MACE),故其在冠脈疾病中得到密切關注[1-2]。ACS患者常會出現心力衰竭、心律失常等心功能異常,嚴重危害患者的生命健康,采取恰當的診斷和治療方式可以顯著降低患者并發癥的產生[3-4]。隨著心電圖技術水平的不斷提高,臨床上發現U波倒置與各類心血管疾病直接相關[5]。本研究主要探討心電圖U波倒置與ACS患者心功能異常的關系,旨在對心電圖U波倒置在ACS診斷中的意義進行研究,現報道如下。

1.1 一般資料
選擇筆者所在醫院2015年1月-2016年12月收治的經冠狀動脈造影(coronary angiography,CAG)確診的ACS患者,共110例,其中男61例,女49例;年齡36~79歲,平均(58.6±7.6)歲。所有患者均滿足中華醫學會心血管病學分會制定的指南確診標準[6],所有患者均排除了陳舊性心肌梗死病史及1月內給予Ⅰ類抗心律失常藥物或洋地黃患者。……
