Magnetocardiography is when we use magnets to see how the heart is functioning. You know how magnets are what keep your drawings on the fridge? Well, when we put magnets near your heart, they can help us see what your heart is doing.
Your heart is like a pump that keeps your blood moving through your body. We can use magnetocardiography to see how your heart is pumping the blood. It's like looking at a movie of your heart in action.
To do magnetocardiography, we put some special sensors on your chest. These sensors can detect the magnetic fields that are created by your heart when it beats. Then we can use a computer to turn all that information into a picture or video of your heart.
Doctors use magnetocardiography to help diagnose heart problems. If there is something wrong with your heart, like an irregular heartbeat or blockage, it will show up in the magnetocardiography picture or video.
So, that's magnetocardiography. It's a way for us to see inside your body without using any needles or cutting you open. It's pretty cool!
