Key result
Esophageal electrocardiography successfully diagnosed a rare case of dual tachycardia in a premature infant, which was effectively treated with oral digoxin to restore sinus rhythm.
Why the study?
To enhance understanding of the diagnosis and management of dual tachycardia in infants.

This first reported case of dual tachycardia in a premature infant highlights the utility of esophageal electrocardiography for accurate diagnosis and the effectiveness of digoxin for management.
Single-case neonatal dual tachycardia experience warrants no practice change; leaves open optimal diagnostic and management strategies.
Objective: To enhance understanding of the diagnosis and management of dual tachycardia in infant. Methods: A retrospective analysis was conducted on the clinical data and management of a infant with dual tachycardia. A review of the relevant literature was also performed. Results: A female infant, born 43 min, was transferred to our hospital's NICU via emergency transfer due to "tachycardia lasting over half an hour after premature birth." To better understand the supraventricular tachycardia an esophageal electrode was inserted, the esophageal electrocardiogram confirmed the diagnosis of dual tachycardia (persistent atrial tachycardia combined with short episodes of ventricular tachycardia). Conclusion: This case provides valuable insight into the diagnosis and management of dual tachycardia in infant. For patients presenting with tachycardia, esophageal electrocardiogram is crucial.

Xu et al. (2026) conducted a case report in Dual tachycardia (n=1). Esophageal electrocardiogram and digoxin was evaluated on Diagnosis and resolution of arrhythmia. Esophageal electrocardiography successfully diagnosed a rare case of dual tachycardia in a premature infant, which was effectively treated with oral digoxin to restore sinus rhythm.
