动态心电图检出无症状性心肌缺血的临床价值

Clinical value of Holter monitoring electrocardiogram in the detection of silent myocardial ischemia

目的:探讨24小时动态心电图对无症状心肌缺血(SMI)的临床价值。方法:回顾性分析520例患者进行24小时动态心电图检测的资料。结果:心肌缺血患者心律失常发生率明显高于无心肌缺血患者;无症状心肌缺血多发生于日间;心率变异性降低与心肌缺血之间有较好的相关性。结论:动态心电图早期检出SMI具有可靠的诊断价值。

Objective：To analyse the clinical value of Hoher monitoring electrocardiogram in the detection of silent myocardial ischemia.Methods：The clinical data in five hundredsand twenty patients with silent myocardial ischemia who were detected by Holter monitoring electrocardiogram twenty patients were analysed retrospectively. Results： In the arrhythmia, the occurring rate of patients with myocardial ischemia was higher than that of the patients without myocardial ischemia. The silent myocardial isehemia was easy to occur in daytime. They had much relativity between decrease of heart rate variability and myocardial ischemia. Conclusion： It had important clinical value that Holter monitoring electrocardiogram detected silent myocardial ischemia in early phase.
