Summary
Written by AI, not yet AICS's view · claude-haiku-4-5-20251001This is a clinical case report of a single newborn with an abnormal heart rhythm detected at a routine visit. The document describes the medical presentation and diagnosis of wide-complex tachycardia in a 7-day-old infant. It is a medical case study focused on diagnosis and treatment of a specific cardiac condition, not a study of child well-being outcomes or interventions.
Key points
- A 7-day-old infant presented with a heart rate of 208 beats per minute
- Wide-complex tachycardia in neonates is uncommon
- Supraventricular tachycardia with aberrant conduction is the most frequent cause
- A superior axis with right bundle branch block pattern suggests fascicular ventricular tachycardia
- Verapamil is identified as the preferred therapy for this condition
Limitations
This is a single clinical case report with no systematic evaluation of outcomes or comparison groups. It cannot provide evidence about the prevalence, prognosis, or treatment effectiveness of neonatal tachycardia in populations.
Abstract
Case summary A 7-day-old previously healthy infant boy born at 36 6/7 weeks gestation was found in a routine well-child visit to have a heart rate of 208 beats/min. Electrocardiogram demonstrated a wide-complex tachycardia morphology while maintaining normal blood pressure and adequate perfusion. Take-home messages Wide-complex tachycardia in neonates is uncommon, with supraventricular tachycardia and aberrant conduction being the most frequent etiology. In the absence of congenital heart disease, a superior axis with right bundle branch block morphology on electrocardiogram is suggestive of fascicular ventricular tachycardia, for which verapamil is the preferred therapy.
