An echocardiogram is an ultrasound of the heart. Also known as a cardiac ultrasound, it uses standard ultrasound techniques to image two-dimensional slices of the heart. The latest ultrasound systems now employ 3D real-time imaging.

An echocardiogram image shows that the human heart has four chambers. Apical view – left side of the heart to the right. Anatomically correct image – heart’s apex at bottom. The trace in the lower left shows the cardiac cycle and the red mark the time in the cardiac cycle that the image was captured.

In addition to creating two-dimensional pictures of the cardiovascular system, an echocardiogram can also produce accurate assessment of the velocity of blood and cardiac tissue at any arbitrary point using pulsed or continuous wave doppler ultrasound. This allows assessment of cardiac valve areas and function, any abnormal communications between the left and right side of the heart, any leaking of blood through the valves (valvular regurgitation), and calculation of the cardiac output as well as the Ejection fraction.

Echocardiography was an early medical application of ultrasound. Echocardiography was also the first application of intravenous contrast-enhanced ultrasound. This technique injects gas-filled microbubbles into the venous system to improve tissue and blood delineation. Contrast is also currently being evaluated for its effectiveness in evaluating myocardial perfusion. It can also be used with Doppler ultrasound to improve flow-related measurements.

Echocardiography is usually performed by cardiologists or cardiac sonographers.


Just want to tell you that I’ve been coming to your Yonge & Eglington office for years. Today there was a different person doing ultrasounds who was absolutely fantastic. Next time I’m due for an ultrasound I will follow her to wherever location she will be at. Very professional & very friendly. Please let her manager know how great she is. But probably knows it already. Thank you.

The ultrasound technician is fantastic! I had my ultrasound appointment switched to the Eglinton location last minute and she came to this location to do my ultrasound! She was on time very professional and very pleasant! She made me feel comfortable and I would recommend the Bluewater imaging located at Wilson and Keele location for future tests! Thank you for a good experience!
