Multifocal atrial tachycardia in two neonates
British Heart Journal
|August 1, 1977
Summary
This study describes an uncommon form of atrial tachycardia in two newborns, characterized by rapid, irregular heart rates detected before birth. Treatment with digoxin successfully restored a normal sinus rhythm, marking a potential first description in neonates.
Area of Science:
- Neonatal cardiology
- Pediatric electrophysiology
- Fetal medicine
Background:
- Atrial tachycardia is a rare cardiac arrhythmia in neonates.
- Early detection of fetal heart rhythm abnormalities is crucial for timely intervention.
Observation:
- Two neonates presented with rapid and irregular pulse rates.
- The abnormal heart rhythm was initially detected via fetal monitoring.
- Postnatal electrocardiograms confirmed multifocal atrial tachycardia or chaotic atrial rhythm.
Findings:
- Both neonates received digoxin for treatment.
- Digoxin therapy led to a gradual reversion of the abnormal rhythm to sinus rhythm.
- This case series may represent the first documented instances of multifocal atrial tachycardia in newborns.
Implications:
- This finding expands the understanding of neonatal arrhythmias.
- Early diagnosis and treatment of multifocal atrial tachycardia in neonates can lead to favorable outcomes.
- Further research is warranted to explore the prevalence and long-term management of this condition in the neonatal population.
