Today I will go to the hospital because I have hour for one echocardiogram ("eco")
An echocardiogram it's a siluet of movements of the heart. During the echocardiogram, high-frequency sound waves make photos of the valves and of the hreat, and help to sonógrafo for evaluate the pumping action of the heart. The "eco" is combinated frequently with one Doppler ultrasound and color Doppler to assess blood flow that runs through the heart valves.

It's so interesting! ;)
