对１６８例胸痛患者进行了２４ｈ动态心电图（ＤＣＧ）监测，与常规心电图（ＥＣＧ）进行对比分析，结果心脏病组７２例，ＤＣＧ检出缺血性ＳＴ－Ｔ改变６２例，心律失常检出６１例，敏感性分别为８６％和８５％。而ＥＣＧ心肌缺血及心律失常的检出率分别为４７％和１７％。非特异性胸痛组９６例，心肌缺血与心律失常的检出率分别为３５％和３７％，而ＥＣＧ无１例心肌缺血，６咧出现偶发房性和／或室性早搏，两组比较差异非常显著（Ｐ＜０．０１），表明ＤＣＧ在胸痛病人的诊断和鉴别诊断中有较高的临床实用价值。
168 cases of chest pain patients were monitored 24h dynamic electrocardiogram (DCG), compared with conventional electrocardiogram (ECG), 72 cases of heart disease results, DCG detected ischemic ST-T changes in 62 cases, arrhythmia detection 61 For example, the sensitivities are 86% and 85% respectively. The detection rate of ECG myocardial ischemia and arrhythmia was 47% and 17% respectively. 96 cases of non-specific chest pain, myocardial ischemia and arrhythmia detection rates were 35% and 37%, respectively, while the absence of ECG myocardial ischemia, 6 blanket occasional atrial and / or premature ventricular contractions, the two groups were compared The difference was significant (P <0.01), indicating that DCG in the diagnosis and differential diagnosis of chest pain patients have a higher clinical value.
