Are you feeling a little anxious about your upcoming cardiac stress test? Don’t worry; we’ve got you covered! Let’s go over what happens during a cardiac stress test so that you can be better prepared. We’ll cover what it is, how long it takes, and what happens before, during, and after the test.

What is a Stress Test?

A cardiac stress test is designed to measure how well your heart works when it’s working hard (or “stressed”). It does this by measuring your heart rate and rhythm as you exercise on a treadmill or stationary bike. The results will help your doctor understand if there are any problems with the way your heart responds to exertion.

How Long Does a Stress Test Take?

The actual stress test itself usually takes about 30 minutes to complete. However, depending on the type of test you’re having, and how busy the lab is, it could take anywhere from 45 minutes to an hour or more. Be sure to allow adequate time for the entire visit (including paperwork) when scheduling your appointment.

How Does a Stress Test Work?

Before the Test: Before beginning the actual test, you’ll meet with a technician who will ask some questions about your medical history and explain what will happen during the procedure. You’ll also be asked to sign some forms consenting to the procedure. After that’s done, you’ll change into comfortable clothes such as shorts and a t-shirt for men or shorts and a tank top for women for exercising.

During the Test: During the actual stress test, you’ll be asked to walk on a treadmill or ride a stationary bike at increasingly difficult levels while hooked up to an electrocardiogram (ECG). An ECG measures your heart’s electrical signals, which can tell your doctor how well it’s functioning under strain. The technician may also have you take medications during the test to increase its effectiveness or accuracy.

After the Test: After completing the stress test, you’ll be able to go home and resume normal activities unless instructed otherwise by your doctor. Your results will be analyzed by both a cardiologist (heart specialist) and an exercise physiologist, who will compare them against standard expected values and look for any signs of abnormal activity in order to diagnose any potential issues with your heart health.


A cardiac stress test can be intimidating, but it doesn’t have to be! By understanding exactly what happens during this procedure—from start to finish—you can go into it feeling more relaxed and prepared than ever before! Knowing that both medical professionals and exercise specialists carefully monitor every step of this process should give you peace of mind knowing that any signs of trouble will be caught quickly, if they exist at all!

Ultimately, taking this proactive approach toward managing your cardiovascular health could help save lives in the long run! If you have any further questions about cardiac stress tests or would like more information about them, don’t hesitate to contact us – we’d love to hear from you!
