An echocardiogram (echo) is an ultrasound assessment of the heart’s structure and function. During an echo test, ultrasound waves from a hand held probe placed on the chest in different locations provide pictures of the heart’s valves and chambers and help the sonographer evaluate the pumping function of the heart. Echo combines 2D images with Doppler ultrasound and colour Doppler to evaluate blood flow through the ventricles and atria and across the heart’s valves. The images are then reviewed by a specialist cardiologist and a comprehensive report is issued. Echos are performed by very experienced and qualified echocardiogram technicians. All Echos are read by specialist trained cardiologists experienced in interpreting the clinical significance of the echo findings.
