Electrophysiology study

An electrophysiology study is like taking a picture of your heart while it's working. Doctors use a thin and flexible tube called a catheter to go inside your body and reach your heart. The catheter helps to measure the electrical signals that tell your heart how to beat.

It's a little like the wires that connect your toys to the batteries, but inside your body! This way, doctors can understand how your heart is working, and if there are any problems with it. They might check to see if your heart is beating too fast or too slow, if the signals are not reaching your heart properly, or if there are any other issues that might be causing your heart to not work properly.

To do this test, you will need to lie down on a table and be given some medicine to make you feel relaxed or asleep. Don't worry; it won't hurt! The catheter is then inserted through a small opening in your skin. The doctor will guide the catheter to your heart and measure the electrical activity to see how it is working.

Sometimes they might even send a little electrical shock through the catheter to test how well your heart is working! Most of the time, doctors will use this information to make a plan to help your heart work better.
