In addition, if a measurement deviates from normality it is necessary for the clinician to gauge the magnitude of such deviation.Īn approach to the description of clinical and echocardiographic variables is to describe the measurement in terms of a Z-score. Therefore, the interpretation of these measurements during childhood presents a unique challenge, in determining whether a given measurement is within the expected range.

In adult practice, ultrasound measurements are often reported with respect to a single “normal range” but this approach is impossible in growing children because the normal range of measurements will be impacted by patient growth and / or patient age. Echocardiographic assessment is integral to patient assessment in the majority of children and decisions with respect to surgery or catheter intervention are frequently based on echocardiographic findings. At the most basic level this typically includes measurement of the child's weight, height and blood pressure at clinic visits.

Measurements are an important part of clinical assessment in the practice of paediatric cardiology.
