动态心电图与经食管心脏电生理检查在心悸病因诊断中的价值比较

Comparison of diagnostic value of ambulatory electrocardiography and esophageal electrophysiological exa-mination on palpitation causes

目的比较动态心电图和经食管心脏电生理检查在心悸人群中的应用价值。方法选取因心悸行动态心电图检查和经食管心脏电生理检查的患者各400、123例,比较两种检查方法的阳性率和对不同类型心律失常检出率的差异。结果动态心电图检出258例心律失常(64.5%),接受经食管心脏电生理检查的患者中检出心律失常90例(73.2%),两种检查方法阳性率间的差异无统计学意义(P>0.05)。动态心电图对频发早搏、房性心动过速、心房扑动和房颤的检出率明显高于经食管心脏电生理检查(P均<0.05)。经食管心脏电生理检查对房室结折返性心动过速、房室折返性心动过速的检出率显著高于动态心电图(P均<0.05)。结论动态心电图和经食管心脏电生理检查均可广泛应用于心悸人群,两者对不同类型心律失常检出率存在差异。

Objective To compare the application value of ambulatory electrocardiography(AECG)and esophageal cardiac electrophysiological examination in the population with palpitation.Methods We selected patients who had undergone AECG and esophageal electrophysiological examination due to palpitation,separately 400 and 123 cases.The positive rate and detection rate of different types of arrhythmia were compared between the two examination methods.Results A total of 258 cases of arrhythmia(64.5%)are detected by AECG while 90 cases(73.2%)were detected by esophageal electrophysiological examination.The positive rate does not vary significantly between the two examination methods(P>0.05).The detection rate of frequent premature beats,atrial tachycardia,and atrial flutter and atrial fibrillation by AECG are significantly higher than those by esophageal cardiac electrophysiological examination(P<0.05).The detection rate of atrioventricular nodal reentrant tachycardia and atrioventricular reentrant tachycardia by esophageal electrophysiological examination are significantly higher than those by AECG(P<0.05).Conclusion Both of AECG and esophageal cardiac electrophysiological examination can be widely used in the population with palpitation.The two testing methods differ in the detection rate of various types of arrhythmia.
