Electrocardiogram interpretation in paediatric patients is challenging. The heart of a neonate differs significantly physiologically from an adult’s; the developing heart also undergoes continuous change until adulthood.
At birth, the right ventricle is dominant because of the high pulmonary vascular resistance present in utero; this domi-nance can persist up to the age of 3 yrs. This is reflected on the ECG by the presence of a right axis and dominant R waves in the right precordial leads. (R wave voltages are greater than S wave voltages, but do not exceed normal limits for age.) T waves are upright for the first week after birth, and then become inverted. The T waves gradually become upright again during adolescence. The physician needs to be aware of the effects that normal physiological changes will have on the ECG, and use age-appropriate reference ranges when interpreting a paediatric ECG.
