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.
