Measuring the QT interval in neonates involves obtaining an ECG and calculating the interval from the onset of the Q wave to the end of the T wave. Due to the high heart rate in neonates, the QT interval is often corrected for heart rate using formulas such as Bazett's formula (QTc = QT / âRR). Corrected QT interval (QTc) values help in standardizing the measurement across different heart rates.
