心电图超声心动图及冠状动脉造影对心肌梗死的诊断探讨

A Diagnostic Probe Infarction (MI) by Means of Electrocardiogram(ECG),Ultrasonic Cardiogram(UCG) and Coronarogragraphy(CAG)

目的:研究心电图(ECG)、超声心动图(UCG)、冠状动脉造影(CAG)对心肌梗死(MI)的诊断价值。方法:对来院的疑诊101例心肌梗死患者进行ECG。UCG、CAG检查比较,结果:以CAG手术结果为标准,在101例疑诊心肌梗死患者中ECG异常者占62.3%,诊断率为80%。UCG异常者占60.6%,诊断率为78%。CAG异常者占80.2%(确诊MI患者78例)。结论:证实ECG、UCG、CAG对MI均具有较高的诊断率,且各有特点,对诊断各具有互补之处,均具有较高的临床诊断价值。

This paper is aimed at studying the diagnostic value ECG, UCG and CAG to MI. The methoct that has been used is checking 101 doubtful Cases at our hospital by means of ECG, UCG and CAG and comparing the results, which are conducted with CAG and the results of operations as reference standards. The remarkable cases of ECG, UCG and CAG are respectively 62.3%,60.6% and 80.2% ; their accuracies of ECG and UCG are relatively 80% and 78 M [There are 78 cases which have been diagnosed accurately]. The results have proved that ECG, UCG and CAG are relatively high specificity and sensitivity to MI with their own characteristics. The three methods complement one another to MI diagnosis. Therefore, they are of great value to clinical diagnosis to MI.
