摘　　要：目的评价食管心房调搏对于房室传导阻滞的诊断价值。方法比较145例心动过缓患者采用食管心房调搏与常规/动态心电图对于房室传导阻滞的检出率并进行随访。结果(1)食管心房调搏对房室传导阻滞的检出率(66.9%)高于常规/动态心电图(51.7%),差异有显著性意义(P<0.05)。(2)阿托品试验前后食管心房调搏对房室传导阻滞的检出率(77.9%,66.9%)差异有显著性意义(P<0.05)。(3)经6～24月随访食管心房调搏检出的22例早期病理性房室传导阻滞患者19例发展为典型房室传导阻滞。结论食管心房调搏对房室传导阻滞等缓慢性心律失常的诊断和鉴别诊断同样具有临床实用价值。Objective To appraise application of Transesophaceal atrial pacing （TEAP）in diagnosis of atrioventricular block （AVB）. Methods Sensitivities of TEAP and routine or dynamic electrocardiogram（ECG） in diagnosing AVB were compared in 145 patients with sinus bradycardia. Results （1） The sensitivity of TEAP in diagnosing AVB was higher than that of routine or dynamic ECG （66.9% vs 51.7%, P〈0.05）. （2）The sensitivity of TEAP in diagnosing AVB increased significantly from 66.9% before to 77.9% after intravenous injection of atropine（P〈0.05）. （3）19 of 22 patients diagnosed as pre-AVB developed AVB during following 6-24 months. Conclusion TEAP is a useful method in diagnosis and prediction of AVB.
