目的:研究探讨老年人心电图的特点及诊断意义。方法:回顾分析我院收治的50例老年急性心肌梗死的临床资料,总结心电图特点。结果:AMI心电图表现有:(1)有明显的ST-T改变,在面向心肌坏死区的导联上出现典型的病理性Q波,可直接确诊的29例(58%)。(2)损伤型ST段抬高和对应性ST段压低13例(26%)。(3)在面向损伤区周围心肌缺血区的导联上出现T波倒置7例(14%)。(4)无任何心电图改变者11例(22%)。结论:心电图能够早期发现心肌梗死,便于医生立刻采取有效措施,降低病死率。
Objective: To study the characteristics and diagnostic significance of electrocardiogram in the elderly. Methods: The clinical data of 50 elderly patients with acute myocardial infarction admitted to our hospital were retrospectively analyzed, and the characteristics of ECG were summarized. Results: The ECGs of AMI were as follows: (1) There were obvious ST-T changes. There were 29 cases (58%) of typical direct pathological Q waves on the leads in the area of myocardial necrosis. (2) 13 cases (26%) of ST segment depression and corresponding ST segment depression. (3) T wave inversion occurred in 7 cases (14%) on the leads facing the ischemic area around the injured area. (4) 11 cases without any ECG changes (22%). Conclusion: Electrocardiogram can detect myocardial infarction in the early stage, and it is convenient for doctors to take effective measures immediately to reduce the case fatality rate.
