The echocardiogram test is about1 hour long, according to the American Heart Association. The test takes place in an operating room, clinic, hospital room or doctor's office and is performed by specially trained technicians. During an echocardiogram, a technician uses high frequency sound waves in order to create a picture of the heart.
Echocardigrams are used by doctors to determine theshape and size of the heart. They are also used to look at the movement and thickness of the heart's walls, according to the American heart Association. By performing an echocardigram, a doctor can determine as to whether or not the heart valves are pumping blood correctly or if the valves are too narrow. Echocardiograms also help to spot infectious growth and tumors that may be negatively affecting the hearts valves.
