目的探讨急性心肌梗塞(AMI)心电图ST-T段改变的离子基础,为临床理解分析心电图提供参考。方法对我院近期收治的12例典型AMI患者不同阶段全导联心电图进行监测,分析心电图ST-T段改变的离子基础;同时与另12例非AMI患者心电图进行比较,从差异的结果分析离子的变化。结果AMI患者心电图ST-T段在不同阶段均有不同程度的改变,并逐渐恢复到基线水平,与心肌细胞离子的变化理论分析相符;而非AMI患者除2例变异型心绞痛外,余均变化不明显,与其相关离子的变化一致。结论熟悉AMI离子的改变对理解心电图及深入分析病情具有指导意义。
Objective To investigate the ionic basis of ST-T changes in acute myocardial infarction (AMI) electrocardiogram and provide a reference for clinical understanding of electrocardiogram. Methods 12 cases of typical AMI patients in our hospital at different stages of monitoring all-lead electrocardiogram monitoring, analysis of ST-T segment of the ECG changes in the ion base; the same time with the other 12 cases of non-AMI patients electrocardiogram were compared from the differences in the results of analysis of ions The change. Results The electrocardiogram ST-T segment of AMI patients varied in different stages and gradually recovered to the baseline level, which was consistent with the theoretical analysis of myocardial cell ion changes. In addition to 2 cases of AMI, Not obvious, consistent with the changes of its related ions. Conclusion Familiarity with the changes of AMI ions is instructive in understanding ECG and in-depth analysis of the disease.
