# Dual tachycardia in a premature infant: a rare case report and literature review

## TL;DR

This paper reports a rare case of dual tachycardia in a premature infant and highlights the importance of esophageal electrocardiogram for diagnosis.

## Contribution

The paper presents a rare clinical case and emphasizes the diagnostic value of esophageal electrocardiogram in infants with tachycardia.

## Key findings

- Dual tachycardia was confirmed using an esophageal electrocardiogram in a premature infant.
- Esophageal electrocardiogram is crucial for diagnosing complex arrhythmias in infants.
- The case adds to the limited literature on dual tachycardia in neonates.

## Abstract

To enhance understanding of the diagnosis and management of dual tachycardia in infant.

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.

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).

This case provides valuable insight into the diagnosis and management of dual tachycardia in infant. For patients presenting with tachycardia, esophageal electrocardiogram is crucial.
