目的分析应用12导联动态心电图对老年冠心病心肌缺血的诊断价值。方法 120例老年冠心病心肌缺血患者,随机分为对照组和观察组,各60例。对照组采取冠状动脉造影进行诊断,观察组采取12导联动态心电图进行诊断。对比两组患者的诊断效果。结果观察组阳性检出率(81.67%)高于对照组(65.00%),差异具有统计学意义(P<0.05);两组高血压、糖尿病、伴有胸痛、阳性伴随胸痛检出率比较,差异无统计学意义(P>0.05)。结论在老年冠心病心肌缺血中,采取12导联动态心电图进行诊断,阳性诊断率明显高于冠状动脉造影诊断,值得临床广泛应用及推广。
Objective To analyze the value of 12-lead ambulatory electrocardiogram in the diagnosis of myocardial ischemia in elderly patients with coronary heart disease. Methods A total of 120 elderly patients with coronary heart disease with myocardial ischemia were randomly divided into control group and observation group, with 60 cases in each group. The control group was diagnosed by coronary angiography, and the observation group was diagnosed by 12-lead Holter. Compare the diagnostic results of two groups of patients. Results The positive rate of the observation group (81.67%) was higher than that of the control group (65.00%), the difference was statistically significant (P <0.05). Compared with the detection rate of chest pain in patients with hypertension and diabetes, The difference was not statistically significant (P> 0.05). Conclusions In elderly patients with coronary heart disease, 12-lead ambulatory electrocardiogram was used for diagnosis. The positive diagnostic rate was significantly higher than that of coronary angiography, which deserved wide application and promotion in clinic.
