“What does the blue and red mean on an echocardiogram?”
I am a 53 year old male. I want to know what does the blue and red mean on an echocardiogram?

The blue means the blood is going away from the probe. The red means the blood is coming towards the probe. The colors are imposed on the blood flow by the computer program. What the probe is actually recording are doppler signals, ultrasound pulses bouncing off the cells that are in the blood. You really need to sit down with a cardiologist reading echo's and see the actual pictures to understand this fully. You are probably looking at still images from the echo video.
The colors indicate blood flow. Red is flow toward the transducer and blue is flow away from the transducer.
