RESUMO
<p><b>OBJECTIVE</b>To study the value of transesophageal atrial pacing (TEAP) in neonates with tachyarrhythmia.</p><p><b>METHODS</b>The clinical data of 26 neonates with tachyarrhythmia who underwent TEAP electrophysiological examination or cardioversion were collected.</p><p><b>RESULTS</b>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.</p><p><b>CONCLUSIONS</b>TEAP is helpful to the diagnosis of tachyarrhythmia in neonates and can bring about a high rate of cardioversion success.</p>
