目的:探讨急性心肌梗死后,心电图检查T波的动态变化和左室功能的相关性。方法:将急性心肌梗死患者分为直立组和倒置组,由具备丰富经验的专业临床检查人员对两组患者进行各项检查,记录患者发生急性心肌梗死后,心电图检查的T波和超声心动图检查的左心室射血分数(left ventricular ejection fraction,LVEF)的变动情况。使用SPSS19.0对结果进行统计学分析。结果:直立组的LVEF明显高于倒置组,差异具有统计学意义(P<0.05),提示直立组患者的左心室功能改善情况要优于倒置组;直立组患者中,急性心肌梗死发生后,T波由倒置恢复为直立的时间间隔越短,患者的LVEF越高(P<0.05)。结论:T波动态变化与急性心肌梗死后左室功能存在明显的相关关系,临床医生应准确理解、掌握两者间相关性,积极地对急性心肌梗死患者进行心电图检查以观察T波动态变化,对患者左心室功能做出判断,从而给予合理、积极的治疗措施。
Objective: To investigate the relationship between T wave dynamic changes and left ventricular function after acute myocardial infarction (ECG). Methods: The patients with acute myocardial infarction were divided into upright group and inverted group. The two groups of patients were examined by experienced professional clinical examiners. The T wave and echocardiogram of ECG were recorded after acute myocardial infarction Check the left ventricular ejection fraction (left ventricular ejection fraction, LVEF) changes. The results were statistically analyzed using SPSS 19.0. Results: The LVEF of the erection group was significantly higher than that of the inversion group (P <0.05), which indicated that the improvement of left ventricular function was better in the erection group than in the inversion group. In the erection group, after the acute myocardial infarction, The shorter the time interval from T wave inversion to upright, the higher the LVEF of patients (P <0.05). Conclusion: The dynamic changes of T wave have a clear correlation with left ventricular function after acute myocardial infarction. Clinicians should understand and grasp the correlation between the two, so they should be positively electrocardiogram examined in patients with acute myocardial infarction to observe the dynamic changes of T wave, Left ventricular function in patients to make judgments, so as to give a reasonable and positive treatment.
