Signal-averaged electrocardiogram
So, you know how your heart beats and it makes a sound like "lub-dub"? Well, scientists want to study your heart to make sure it's healthy and working the way it should. One way they can do this is by taking an electrocardiogram (ECG for short), which is like taking a picture of your heart's activity.
But sometimes, it can be hard to see if your heart is having any problems from just one ECG picture. So, scientists came up with a way to take lots of pictures of your heart's activity and average them together to get a better picture. This is called a signal-averaged electrocardiogram (SAECG for short).
It's like if you take lots of pictures of your face and average them together to get one really clear picture of what you look like. Scientists use special machines to take lots of pictures (or signals) of your heart and then average them together.
This way they can see if your heart is having problems that might be hard to see in just one picture. It's kind of like having a bunch of friends take pictures of you and then putting them together to make sure you look good from all angles.
