心肌梗死超急性期50例诊断分析

Diagnosis analysis of super acute period of myocardial infraction in 50 cases

目的探讨心电图和超声心动图两种方法诊断心肌梗死超急性期的灵敏性、准确性。方法将50例心肌梗死超急性期患者随机分为心电图组和超声心动图组,比较确诊、漏诊、误诊率及对心肌梗死定位、并发症的检测和评估。结果超声心动图组确诊率(84%)明显高于心电图组(56%),差异具有统计学意义(P<0.05)。结论超声心动图不仅能对心肌梗死超急性期迅速作出准确诊断,还能评估心肌梗死面积、心肌受损程度、心肌存活性、左心功能、机械并发症,超声心动图组诊断方法优于心电图组。

Objective To compare the sensitivity and accuracy of super acute period myocardial infarction diagnose by electrocardiogram and ultrasonic cardiogram.Methods Fifty cases of myocardial infarction of super acute period patients were randomly divided into two groups（electrocardiogram group and ultrasonic cardiogram group）,the diagnosis rate,misdiagnosis rate,infraction location and complications were observed and compared.Results The diagnose rate of ultrasonic cardiogram group was obviously higher than electrocardiogram group（84% vs 56%,P0.05）.Conclusions Ultrasonic cardiogram can diagnose the acute myocardial infarction quickly and accurately,and can evaluate the area of infraction,the level of heart injury,the left heart function and complication.The ultrasonic cardiogram is better than electrocardiogram in diagnosis of acute myocardial infraction.
