目的应用食管导联心电图对阵发性室上性心律失常的检出率分析。方法应用双极食管导联心电图记录180例和单极食管导联心电图记录70例对各类阵发性室上性心律失常的检出率对照分析。结果房室结双径路在双极食管导联心电图的检出率为82.22%,单极食管导联心电图的检出率为57.14%,P<0.01;预激综合征合并房室折返性心动过速在双极导联食管心电图的检出率为11.66%,单极食管导联心电图的检出率为10.00%,P<0.05。结论双极食管导联心电图对阵发性室上性心律失常的检出率比单极食管导联心电图的检出率高,安全、可靠、实用、能定位,对射频消融术前病例的筛选具有重要作用。
Objective To analyze the detection rate of paroxysmal supraventricular arrhythmia by esophageal lead electrocardiogram. Methods The bipolar esophageal lead electrocardiogram was recorded in 180 cases and unipolar esophageal lead electrocardiogram recorded in 70 cases of various types of paroxysmal supraventricular arrhythmia detection rate of control analysis. Results The detection rate of bipolar esophageal lead electrocardiogram was 82.22%. The detection rate of unipolar esophageal lead electrocardiogram was 57.14% (P <0.01). Pre-excitation syndrome combined with atrioventricular reentrant tachycardia The detection rate of bipolar lead esophageal electrocardiogram was 11.66%. The detection rate of unipolar esophageal lead electrocardiogram was 10.00% (P <0.05). Conclusions The detection rate of bipolar esophageal lead electrocardiogram to paroxysmal supraventricular arrhythmia is higher than that of unipolar esophageal lead electrocardiogram. It is safe, reliable, practical and able to locate. The screening of pre-radiofrequency ablation preoperatively has Important role.
