目的比较Holter和普通心电图对于冠心病的诊断价值。方法随机选择300例冠心病病人,分别做12导联Holter(动态心电图)和普通12导联心电图,统计两组发生各种心律失常类型的人数,以及心肌缺血阳性的人数(包括有症状缺血与无症状缺血的人数),并统计分析Holter组和ECG组间的差异。结果 1心律失常特征:普通心电图组阳性187例,阴性113例,阳性率62.3%,Holter组阳性256例,阴性44例,阳性率85.3%,尤其二联律、三联律、成对的房性早搏和室性早搏、短阵室上速阳性率明显增加,差异有统计学意义(p<0.05)。Holter组整体上心律失常的阳性率明显高于心电图组,差异有统计学意义(p<0.05);2心肌缺血:ECG组心肌缺血阳性166例,阴性134例,阳性率52.3%,无症状缺血20例,阳性率6.7%。Holter组心肌缺血阳性248例,阴性52例,阳性率80.2%,无症状缺血215例,阳性率71.7%。Holter组对心肌缺血,尤其无症状缺血的阳性率,要显著高于普通心电图组,差异有统计学意义(p<0.05)。结论 Holter对冠心病心律失常和心肌缺血的诊断阳性率明显高于普通心电图,故Holter对冠心病有较高的诊断价值。
Objective To compare the diagnostic value of Holter and general electrocardiogram in coronary heart disease. Methods A total of 300 patients with coronary heart disease were randomly divided into 12-lead Holter and 12-lead electrocardiogram. The number of patients with various types of arrhythmia and the number of patients with positive myocardial ischemia (including those with symptoms Blood and asymptomatic ischemia), and statistical analysis Holter group and ECG differences between groups. Results 1 Arrhythmia characteristics: 187 cases of normal electrocardiogram positive group, negative 113 cases, the positive rate of 62.3%, Holter group positive 256 cases, negative 44 cases, the positive rate of 85.3%, especially the second law, triple law, paired atrial Premature beats and premature ventricular contractions, supraventricular tachycardia rate was significantly increased, the difference was statistically significant (p <0.05). Holter group, the overall positive rate of arrhythmia was significantly higher than the ECG group, the difference was statistically significant (p <0.05); 2 myocardial ischemia: ECG group of myocardial ischemia positive 166 cases, negative 134 cases, the positive rate of 52.3%, no Symptoms of ischemia in 20 cases, the positive rate of 6.7%. Holter group had 248 cases of myocardial ischemia, 52 cases were negative, the positive rate was 80.2%, and 215 cases were asymptomatic ischemia, the positive rate was 71.7%. Holter group of myocardial ischemia, especially asymptomatic ischemia positive rate was significantly higher than the normal ECG group, the difference was statistically significant (p <0.05). Conclusion Holter on coronary heart disease arrhythmia and myocardial ischemia positive rate was significantly higher than the common ECG, so Holter of coronary heart disease have a higher diagnostic value.
