Stress Testing Q & A

What is stress testing?

Stress testing is a procedure that raises your heart rate and makes your heart pump harder. It can identify cardiac conditions and abnormalities that don’t show when you have a regular test.

The most common type of stress testing uses an electrocardiogram (EKG), which measures the electrical activity in your heart during exercise. Other types of stress testing include:

Nuclear stress testing

This type of stress testing requires you to have an injection of radioactive material into your bloodstream. The material shows up on imaging technology, helping to highlight damaged tissues and poor blood flow.

Stress echocardiography

An echocardiogram creates moving images of your heart using ultrasound technology. It's particularly useful for identifying structural and valvular problems.

Heart and Vascular of Central Texas also uses cutting-edge techniques like perfusion imaging to diagnose even the most challenging heart problems.

Why might I need a stress test?

One of the main reasons for undergoing stress testing is to determine the cause of symptoms that seem to be heart-related but aren't identifiable on a standard EKG or echocardiogram.

Stress testing is a useful method of monitoring your condition if you have a heart condition and you're receiving treatment. It enables your provider to make adjustments to your treatment plan that optimize your recovery.

If you're awaiting cardiac surgery, stress testing can help confirm whether you're ready for the procedure. It's also a valuable tool for assessing whether you need major surgery like a heart transplant in the first place.

What happens when I have a stress test?

The process of undergoing stress testing varies as there are different types of tests. A straightforward exercise stress test takes about an hour. You might have instructions to follow about when and if you should stop eating, drinking, smoking, and taking medication.

First, your technician attaches the monitoring equipment, for instance sticking electrodes on your skin for the EKG. You start exercising on a treadmill or stationary bicycle, gradually increasing your effort according to your provider's instructions.

The phase during which you're exercising most vigorously only lasts about 15 minutes. However, if you're unable to exercise, you can take a medicine that makes your heart behave in the same way.

Your provider might perform tests before, during, and after you exercise to gather as much information about your heart function as possible.
