R波递增不良诊断前壁心肌梗死价值研究

Research on Value of Clinica Diagnosis of Increamental Electrocardiogram R wave on Adverse Reactions of Anterior wall myocardial infarction

目的研究心电图R波递增不良在临床对前壁心肌梗死的临床诊断价值。方法研究时间为2008年1月~2014年12月,对象选择为2400例心电图检查中均出现R波递增不良的患者,根据病变的不同将其分为器质性病变组（1400例）和非器质性病变组（1000例）,分别在不同的标准下进行前壁心肌梗死的诊断。结果分别参照Wamer、Depace、Zema、Marquette四种常规诊断标准,器质性病变组诊断率平均在30.0%~45.0%,非器质性病变组诊断率平均在3.0%~9.0%,器质性病变组诊断率高于非器质性病变组,组间具有显著统计学差异（p〈0.05）。以超声心动图检查结果为标准,心电图R波递增不良与前壁心肌梗死具有显著相关性（p〈0.01）。结论临床对前壁心肌梗死的诊断标准不一,心电图R波递增不良可对前壁心肌梗死进行诊断,但诊断率不高,在临床使用中具有一定的局限性。

Objective This paper is to investigate clinical diagnosis value of poor R wave progressions of Electrocardiograms（ECG） applied in anterior wall myocardial infarction. Methods 2400 patients with poor R wave repressions in ECG examination admitted from January, 2008 to December, 2014 were selected as research subjects,who were divided into organic lesion group（1400 cases） and non-organic lesion group（1000 cases）, and they underwent the diagnosis of anterior wall myocardial infarction respectively under different criterias. Results Four routine diagnostic criterions including Wamer, Depace, Zema and Marquette are respectively referred, average diagnosis rate for patients in organic lesion group ranged from 30.0% to 45.0% on average, and that value of patients in non-organic lesion group ranged from 3.0% to 9.0%, the diagnosis rate on organic diseases was higher than that on patient in non organic lesion group, and the inter-group difference was statistically significant difference（p〈0.05）.MPI test results were treated as standard, and poor R wave repression was significantly associated with anterior wall myocardial infarction（p〈0.01）. Conclusions There were different clinical diagnosis criterions for anterior wall myocardial infarction, poor repression of electrocardiogram R wave may be used to diagnose anterior wall myocardial infarction, but the diagnosis rate was not high, delivering certain limitation in clinical services.
