【摘要】 目的研讨食道心房调搏对房室结折返性心动过速的诊断价值,为房室结折返性心动过速的诊断及进一步导管射频消融治疗提供指导及诊断依据。方法通过分析统计69例心动过速患者食道心电图,并分析其S₂R跃增值、RP’E间期等数值,将研究结果与心内电生理检查结果进行对比,计算食道心房调搏对房室结折返性心动过速诊断的敏感性、特异性及准确性。结果与心内电生理检查相比,食道电生理检查对房室结折返性心动过速诊断无明显差异,对房室结折返性心动过速诊断有较高的敏感性、特异性及准确性。结论食道心房调搏是一种安全、有效的诊断房室结折返性心动过速的方法,可在临床中作为必要检查,同时对导管射频消融具有指导作用更多还原

【Abstract】 Objective To study esophageal atrial pacing in patients with atrioventricular nodal reentrant tachycardia diagnostic value for tachycardia, atrioventricular nodal reentry tachycardia and further the diagnosis speed catheter radiofrequency ablation in the treatment of providing guidance and diagnosis. Methods Through the statistical analysis of 69 cases of tachycardia in patients with esophageal electrocardiogram, and analysis of the S₂R, RP’E interval numerical value step, the research results and intracardiac electrophysiological examination results were compared, the calculation of transesophageal atrial pacing atrioventricular nodal reentrant tachycardia diagnostic sensitivity, specificity and accuracy. Results Compared with the cardiac electrophysiological examination, there was no significant difference in the diagnosis of atrioventricular nodal reentry tachycardia. The sensitivity, specificity and accuracy of the diagnosis of atrioventricular nodal reentry tachycardia were higher. Conclusion Esophageal atrial pacing is a safe and effective method in the diagnosis of atrioventricular nodal reentry tachycardia. It can be used as a necessary check in clinical practice.更多还原
