Cardiac stress test

A cardiac stress test is like a game for your heart, where you run or walk on a treadmill or bike while the doctors watch your heart. They want to see how well your heart can handle moving and working hard.

Before the test, you will have stickers put on your chest with wires attached to a machine that measures your heart rate and rhythm. Then, you will be asked to walk on a treadmill or bike for a few minutes while the machine records your heart activity.

As you keep going, the treadmill will get faster and steeper or the bike will get harder, so your body has to work harder. This is like the game getting harder! The doctors will keep an eye on you and ask how you feel.

Once the test is finished, the doctors will compare the results of your heart activity at rest and when you were exercising. They will be able to see how your heart reacts to stress, which helps them figure out if there are any problems that need to be treated.

Overall, the cardiac stress test is like a game that helps doctors understand how your heart works when it is under pressure.
