Stress Test Q & A

What is stress testing?

A stress test shows how well your heart performs when increased physical activity forces it to pump more blood. Evaluating the electrical activity in your heart while at rest and when exercising or under stress provides important information about the heart’s overall health. Additionally, some heart problems only occur when you’re active.

When would I need to have stress testing?

Stress testing helps to:

  • Diagnose coronary artery disease
  • Diagnose heart arrhythmias
  • Diagnose heart valve problems
  • Diagnose heart failure
  • Detect problems with blood flow in your heart
  • Determine the best treatment for a heart condition
  • Evaluate the effectiveness of heart treatments

Your provider at Trident Cardiology Associates, PA, may also perform a stress test to determine a safe level of exercise.

What happens during a stress test?

Your provider places electrodes on your chest and connects them to an electrocardiogram (ECG) machine. The ECG records your heart’s electrical activity before and during your stress test. You also wear a blood pressure cuff so your provider can check your blood pressure while you exercise. 

During most stress tests, you walk on a treadmill. This exercise stress test starts slowly. Then your provider gradually increases the speed of the treadmill to boost your heart rate.

The stress test continues until you reach your peak heart rate or develop uncomfortable symptoms. Highly trained medical professionals stay with you throughout the stress test, so you have immediate care if you don’t feel well.

What other type of stress testing might I have?

In addition to exercise stress testing, your provider may perform one of the following:

Pharmacologic stress test

If you can’t tolerate exercise or have difficulty walking on the treadmill, your provider injects medications that increase your heart rate. Your provider may use Adenocard®, Lexiscan®, or Dobutrex®.

Nuclear stress test

During a nuclear stress test, your provider combines nuclear imaging with a stress test. They perform nuclear imaging by injecting a radioactive dye into your bloodstream. Then a specialized machine picks up the radiation, creating images of the blood as it flows through your heart.

They take an image before and after your stress test and compare the differences in blood flow. A nuclear stress test provides details about blood flow problems that don’t appear on other types of imaging. 

Stress echocardiogram

Your provider takes an echocardiogram before and after your stress test. Echocardiograms use ultrasound to produce images of your heart.
