Single-centre retrospective analysis of the best timing for the QTc interval length assessment in neonates.

ABSTRACT:

Objective

To evaluate the best timing for ECG screening in order to diagnose long QT syndrome and lower, at the same time, the false positives.

Design

We retrospectively evaluated the corrected QT (QTc) interval in the clinical reports of the ECG screening performed, as per internal protocol.

Setting

An outpatient setting in our Unit of Neonatology and Pediatrics, Santa Maria Goretti Hospital in Latina, Italy.

Patients

We enrolled 3467 healthy neonates between 14 and 30 days of life.

Interventions

The newborns with abnormal QTc interval were invited to subsequent revaluation every 21 days, until normalisation or necessity to refer to a tertiary paediatric cardiology centre.

Main outcome measures

Difference in QTc according to patients' characteris
