Abstract：Objective To study the value of transesophageal atrial pacing (TEAP) in neonates with tachyarrhythmia. Methods The clinical data of 26 neonates with tachyarrhythmia who underwent TEAP electrophysiological examination or cardioversion were collected. Results Of the 26 neonates, 15(58%) were diagnosed with atrioventricular reentrant tachycardia, 3(12%) were diagnosed with sinus tachycardia, 3(12%) were diagnosed with ventricular tachycardia, 2(8%) were diagnosed with fast/slow atrioventricular nodal reentrant tachycardia, 2(8%) were diagnosed with atrial tachycardia, and 1(4%) was diagnosed with sinus tachycardia with ventricular preexcitation. Overdrive suppression was performed for 22 neonates, among whom 18 achieved successful cardioversion, and 2 with atrial tachycardia and 2 with ventricular tachycardia failed to restore sinus rhythm. Conclusions TEAP is helpful to the diagnosis of tachyarrhythmia in neonates and can bring about a high rate of cardioversion success.
