Abstract:Objective To discuss the diagnostic value of trans-esophageal atrial pacing (TEAP) for arrhythmias. Methods During the past 26 years select 12 830 patients who suffered recurrent palpitation, dizziness and brief syncope and accepted TEAP examination. Statistically analyze the results and get knowledge of the occurrences of different arrhythmias. Results The inducing rate of arrhythmia is 61.23%.The morbidity of supraventricular tachycardia (SVT) is obviously higher than that of ventricular tachycardia (VT) (SVT, 50.35% vs. VT, 1.23%), with a statistically significant difference (P<0.05). By TEAP overdrive suppression, 99.83% of SVT are successfully terminated and 0.15% fail (Patients who require to terminate TEAP don’t be counted), also with a statistically significant difference (P<0.05).No severe complications occur to patients during the examination. Conclusion It’s one of the most effective non-invasive treatments to utilize TEAP in inducing and terminating VT. The method can provide reliable basis for further clinical treatment, and therefore deserves to be widely promoted and applied.
