摘　　要：目的分析动态心电图对心房颤动合并Ⅱ度房室传导阻滞的诊断价值。方法选取2021年2月至2023年10月收治的108例房颤合并房室传导阻滞患者作为研究对象,按照疾病类型差异将其分为房室传导阻滞Ⅰ度组(30例)及房室传导阻滞Ⅱ度组(78例),再将房颤合并Ⅱ度房室传导阻滞患者按照是否出现黑矇、心悸、晕厥以及头晕等症状分为有症状组及无症状组。比较不同组别患者各项动态心电图指标;绘制受试者工作特征(ROC)曲线明确各项动态心电图指标诊断房颤合并Ⅱ度房室传导阻滞的效能。结果房室传导阻滞Ⅰ度组的颤动发生次数、平均心室率高于房室传导阻滞Ⅱ度组,长间歇时间短于房室传导阻滞Ⅱ度组(P<0.05)。ROC曲线结果显示,颤动发生次数、长间歇时间及平均心室率诊断房颤合并Ⅱ度房室传导阻滞的曲线下面积(AUC)分别为0.945、0.823、0.947(P<0.05)。房颤合并Ⅱ度房室传导阻滞患者有症状者35例,无症状者43例。有症状组的颤动发生次数、平均心室率均低于无症状组,长间歇时间长于无症状组(P<0.05)。结论动态心电图诊断房颤合并Ⅱ度房室传导阻滞的效能较佳,可有效指导临床对症处理,促进患者病情改善。Objective To analyze the diagnostic value of dynamic electrocardiogram in atrial fibrillation withⅡdegree atrioventricular block.Methods A total of 108 patients with atrial fibrillation complicated with atrioventricular block admitted from February 2021 to October 2023 were selected as the research objects.According to the difference of disease types,the patients were divided into atrioventricular blockⅠdegree group(30 cases)and atrioventricular blockⅡdegree group(78 cases).Then the patients with atrial fibrillation complicated with atrioventricular blockⅡdegree were divided into symptomatic group and asymptomatic group according to whether there were symptoms such as amaurosis,palpitation,syncope and dizziness.The dynamic electrocardiogram indexes of patients in different groups were compared;the receiver operating characteristic(ROC)curve was drawn to determine the efficacy of each dynamic electrocardiogram index in the diagnosis of atrial fibrillation withⅡdegree atrioventricular block.Results The frequency of fibrillation and average ventricular rate in the atrioventricular blockⅠdegree group were higher than those in the atrioventricular blockⅡdegree group,and the long interval time was shorter than that in the atrioventricular blockⅡdegree group(P<0.05).ROC curve results showed that the area under curve(AUC)of the frequency of fibrillation,long interval time and average ventricular rate in the diagnosis of atrial fibrillation withⅡdegree atrioventricular block were 0.945,0.823 and 0.947,respectively(P<0.05).There were 35 symptomatic patients and 43 asymptomatic patients in patients with atrial fibrillation complicated withⅡdegree atrioventricular block.The frequency of fibillations and average ventricular rate in the symptomatic group were lower than those in the asymptomatic group,and the long interval time was longer than that in the asymptomatic group(P<0.05).Conclusion The efficacy of dynamic electrocardiogram in the diagnosis of atrial fibrillation combined with second-degree atriov
