Abstract: Objective　To explore the value of transesophageal atrial pacing (TEAP) and temporary cardiac pacing in the treatment of acute intractable tachyarrhythmia in children. Method　The clinical data of children with acute intractable tachyarrhythmia treated with TEAP (48 cases) or temporary cardiac pacing (6 cases) from January 2014 to December 2017 were retrospectively analyzed. Results　In the 48 cases aged 1 day to 13 years (28 males and 20 females) treated with TEAP,  25 cases had paroxysmal supraventricular tachycardia,  in which there were 15 cases of rapid atrial flutter, 5 cases of atrial tachycardia and 3 cases of left ventricular idiopathic bundle branch reentrant tachycardia. The rates of successful cardioversion to sinus rhythm through TEAP were 84%, 80%, 20% and 100% respectively. In the 6 cases aged 2 to 10 years (1 male and 5 females) treated with temporary cardiac pacing, there were 5 cases of fulminant myocarditis and 1 case of noncompaction of the ventricular myocardium and their conditions were well controlled after treatment. Conclusion　TEAP and temporary cardiac pacing have good curative effect in the treatment of acute intractable tachyarrhythmia in children. However, temporary electricity therapy can only temporarily rectify the hemodynamic abnormality threatening the life of children, and active comprehensive treatment for the primary diseases should be carried out simultaneously.
