What do an ECG and heart ultrasound show, and why are they different tests?
An ECG and a heart ultrasound assess different aspects of the heart and do not replace one another. An electrocardiogram (ECG) helps assess the heart rate and rhythm and detect abnormalities in heart rhythm and conduction.
A heart ultrasound (echocardiography) allows the doctor to evaluate the heart’s structure, the size of its chambers, the condition of the valves, and its contractile function.
Combining these tests can be particularly important if a child experiences palpitations, an irregular heartbeat, chest pain, shortness of breath, dizziness, fainting, or unusual fatigue. A comprehensive cardiac assessment may also be recommended if a heart murmur has been detected, after certain illnesses when medically indicated, or before intensive physical activity.
The pediatric cardiorheumatologist interprets the ECG and heart ultrasound findings together with the child’s symptoms, physical examination, and medical history. This provides a more complete assessment of the child’s heart health and helps determine whether treatment, additional diagnostic tests, or further follow-up are needed.
From symptoms to a medical conclusion: a comprehensive assessment in one visit
The pediatric cardiorheumatologist evaluates the child’s symptoms, clinical findings, ECG, and heart ultrasound as part of a single consultation.
The consultation begins with a review of the child’s symptoms, previous illnesses, family medical history, and level of physical activity. The doctor performs a clinical examination, assesses the heart rate, blood pressure, and other relevant clinical findings, and then interprets the ECG and heart ultrasound results in the context of the information obtained during the consultation.
A pediatric cardiorheumatologist may be consulted for joint pain or swelling, persistent fever without an established cause, or other symptoms that may be associated with inflammatory or systemic conditions. In such cases, the doctor evaluates the overall clinical picture and determines which additional examinations may be necessary.
Following the consultation, parents receive a medical report and recommendations on the next steps. When indicated, the pediatric cardiorheumatologist may order laboratory tests, recommend additional diagnostic examinations, follow-up monitoring, or consultation with another specialist.
