What Is an Exercise Stress Test?
An exercise stress test, also called a cardiac stress echocardiogram, involves walking on a treadmill or riding a stationary bike while your heart is monitored. A special ultrasound probe is placed on your chest to capture images of your heart’s structure and function during rest and exercise. This helps doctors evaluate how well your heart pumps blood and detects any areas with reduced blood flow or damage.
How Is the Test Performed?
You’ll start by lying down while your heart is checked with an ultrasound. Then, you’ll walk or ride a bike at a controlled pace. Your heart rate, blood pressure, and ECG are continuously monitored. If you cannot exercise, you may receive medication to simulate stress on your heart.
Preparation and Safety
No special preparation is needed, but wear comfortable clothing and shoes suitable for exercise. Bring your medications with you. You’ll be monitored closely for any signs of discomfort or unusual symptoms, such as chest pain, dizziness, or shortness of breath.
What to Expect During Recovery
After the test, you’ll rest for a short period before leaving. You may feel tired or have mild soreness, but severe symptoms should be reported immediately. Avoid heavy lifting or strenuous activity for the rest of the day.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
This test helps identify coronary artery disease, heart muscle damage (such as from a heart attack), or other heart conditions. It can also guide decisions about exercise, medications, or procedures like angioplasty or bypass surgery. Results may show how well your heart functions under stress, which is crucial for managing long-term heart health.
