心电图在急性心肌梗死超急性期诊断中的应用(1)
[摘要] 目的 分析心電图在诊断急性心肌梗死超急性期的应用价值。 方法 方便选择该院(2014年6月—2016年7月)急性心梗超急性期患者120例，按照病程分为A组(75例)，B组(25例)，C组(20例)，A组病程<2 h，B组2 h6～8 h。3组患者性别、年龄、病程等基本资料相比，且差异无统计学意义(P>0.05)。利用心电图机对所有患者进行24 h不间断心电监测，观察记录A、B、C 3组心电图T波、Q波、ST段的变化情况，对比其阳性变化率。结果 A组发生心电图阳性变化有61例，其心电图阳性变化率为81.30%；B组发生心电图阳性变化有10例，其心电图阳性变化率为40.00%；C组发生心电图阳性变化有4例，其心电图阳性变化率为20.00%。将A、B、C 3组患者心电图阳性变化率进行对比，其中A组心电图阳性变化率较B、C两组高，差异有统计学意义(P<0.05)。在患者病发2 h内，观察ST段抬高与非抬高情况，把心梗患者分为ST段抬高型急性心肌梗死和ST非抬高型急性心肌梗死两种类型，其中属于ST段抬高型急性心肌梗型死有55例，其心电图诊断阳性例数为19例，心电图阳性率为34.54%；属于ST非抬高型急性心肌梗死型有23例，其心电图诊断阳性例数为4例，，心电图阳性率为17.39%，ST段抬高型急性心肌梗死型心电图诊断阳性率较ST非抬高型急性心肌梗死型患者高，差异有统计学意义(P<0.05)。结论 针对急性心梗超急性期患者采取24 h心电监测，可以对患者病情做出准确判断，便于及时采取有效治疗措施。

[Abstract] Objective To analyze the application value of electrocardiogram in the diagnosis of acute myocardial infarction during the super acute period. Methods 120 cases of patients with acute myocardial infarction during the super acute period from June 2014 to July 2016 were convenient selected and divided into two groups， the group A(75 cases) disease course < 2 h， group B(25 cases) disease course 2～6 h， and the group C(20 cases) disease course > 6～8 h， and the differences in the gender， age and disease course between groups were not statistically significant(P>0.05)， and the 24 h electrocardiogram monitoring were given to all patients， and the T wave， Q wave and ST segment changes in the three groups were observed and recorded， and the positive change rate was compared. Results In the group A， there were 61 cases with electrocardiogram positive changes， and the change rate was 81.30%， in the group B， there were 10 cases with electrocardiogram positive changes， and the change rate was 40.00%， and in the group C， there were 4 cases with electrocardiogram positive changes， and the change rate was 20.00%， and the comparison showed that the change rate in the group A was higher than that in the group B and group C， and the differences were obvious with statistically significant(P<0.05)， and the myocardial infarction patients were divided into the acute st-segment elevation myocardial infarction group with 55 cases whose positive rate of electrocardiogram was 34.54%(19 cases) and the non-st segment elevated myocardial group with 23 cases whose positive rate of electrocardiogram was 17.39%(4 cases) and the difference was statistically significant(P<0.05). Conclusion The 24 h electrocardiogram monitoring of acute myocardial infarction patients during the super acute period can accurately determine the disease condition of patients， and it is conducive to adopting the effective treatment measures in time., http://www.100md.com(翟晓华)
