Key result
Practical framework guides diagnostic investigations and specialist cardiology referral for managing neonatal bradycardia.
Why the study?
Neonatal bradycardia is often self-resolving but can indicate cardiac or non-cardiac pathology, necessitating a practical framework to guide investigation and specialist referral.
How should neonates with bradycardia be investigated and managed?
How should neonates with bradycardia be investigated and managed?
Provides a practical framework for the diagnosis and management of neonatal bradycardia, highlighting both cardiac and non-cardiac causes.
May guide neonatal bradycardia evaluation and referral; leaves open prospective validation of the framework.
Neonatal bradycardia is characterised by a heart rate below 80 bpm, irrespective of gestational age. It is generally self-resolving but, in some cases, represents an underlying pathology which may be cardiac or non-cardiac in origin. The common causes for bradycardia are non-cardiac in origin such as autonomic immaturity in premature infants, electrolyte imbalances, hypothyroidism and medications. Cardiac causes include-sinus bradycardia, conduction system abnormalities, congenital heart disease and channelopathies. Diagnostic investigations typically include a standard 12-lead ECG, 24-hour Holter monitor and an echocardiogram. This article aims to provide a practical framework for the management of neonates with bradycardia and guide further investigation and/or referral to specialist paediatric cardiology services.

Shrestha et al. (2024) conducted a review in Neonatal bradycardia. Management framework for neonatal bradycardia was evaluated. A practical framework for the management of neonatal bradycardia is provided to guide diagnostic investigations and referral to specialist paediatric cardiology services.
