Abstract：Objective To investigate the significance of transesophageal electrophysiological examination in the diagnosis and treatment of rapid atrial arrhythmia. Methods The course and mechanism of diagnosis and treatment of 5 patients with rapid atrial arrhythmia by transesophageal electrophysiological examination were analyzed retrospectively. Results Through the atrial mapping, the Pwave amplitude of transesophageal electrophysiological examination is increased It has obvious advantages in the diagnosis of rapid atrial arrhythmia compared with surface electrocardiogram, and it can also be used as a treatment to stop the attack of tachycardia. Conclusion As a noninvasive cardiac electrophysiological examination technology, transesophageal cardiac electrophysiological examination can diagnose, induce and terminate tachycardia and provide help for clinical diagnosis and treatment.
