What does the loud squeaky sound during an echocardiogram mean?

Question

I have high blood pressure and had an echocardiogram today.

Answer 1

cmh - You ask a very good question. Sometimes, when people are getting an echocardiogram, they may hear the machine make rhythmic swishing and clicking noises. Remember that an echocardiogram uses reflected sound waves to generate a picture of your heart. One thing the echo machine can do is use these sound waves to determine the direction that blood is flowing and how fast. When this function (called Doppler) is in use, the machine will turn these reflected waves into sounds that we can hear. The clicks are the sound of the valves shutting and the whooshing sounds represent blood flow. Hearing these sounds doesn't mean that anything is or isn't wrong with your echocardiogram, but it can be a little disconcerting if you don't know what you're listening to! To find out what your echo showed, you need to review it with your doctor. Hope that helps!
