12导联动态心电图在老年冠心病患者心肌缺血和心律失常诊断中的价值分析

Diagnostic Value of 12-lead Synchronous Ambulatory Electrocardiogram in Elderly Coronary Heart Disease Patients with Myocardial Ischemia and Arrhythmia

目的:探讨12导联动态心电图对老年冠心病患者心肌缺血、心律失常的诊断价值。方法:临床纳入笔者所在医院2015年2月-2018年2月收治的80例老年冠心病患者作为研究对象,随机将全部入选者分为研究组、对照组,各40例。对照组患者行常规心电图检查,研究组患者进行12导联动态心电图检查,分析对比两组检测结果及心律失常情况。另外,将两组心律失常检出率进行分析对比。结果:研究组心肌缺血阳性、ST段抬高、ST段压低检出率与对照组相比明显更高,差异均有统计学意义(P<0.05);研究组房性逸搏、室性心动过速、短阵室上速、心房颤动等检出率较对照组明显更高,差异均有统计学意义(P<0.05);研究组患者早发、成对检出率与对照组相比明显更高,差异均有统计学意义(P<0.05)。结论:对老年冠心病患者而言,12导联动态心电图的运用具有重要临床意义,在诊断老年冠心病患者心律失常、心肌缺血方面优势明显,具备较高临床诊断价值。

Objective:To discuss the diagnostic value of 12-lead synchronous ambulatory electrocardiogram in elderly coronary heart disease(CHD)patients with myocardial ischemia and arrhythmia.Method:A total of 80 elderly CHD patients treated from February 2015 to February 2018 in the author,s hospital were selected.The subjects were randomly assigned to study group and control group,40 cases each group.Patients received the conventional electrocardiogram or 12-lead synchronous ambulatory electrocardiogram,respectively.The examination results and detection rate of arrhythmia were counted.Result:The positive rate of myocardial ischemia,detection rate of ST-segment elevation and ST-segment depression in the study group were significantly higher than control group(P<0.05).The detection rate of atrial escape beat,ventricular tachycardia,paroxysmal supraventricular tachycardia and atrial fibrillation in the study group were significantly higher than control group(P<0.05).The detection rate of early-onset beats and paired beats in the study group were significantly higher than control group(P<0.05).Conclusion:The 12-lead synchronous ambulatory electrocardiogram is of great importance to the diagnosis of arrhythmia and myocardial ischemia.
