Stress Tests Test
A stress test checks how well your heart works when it's pumping hard, usually while you exercise on a treadmill or stationary bike. If you can't exercise, medicine can make your heart work harder instead.
What this test measures
Stress tests measure blood flow in your heart, your blood pressure, the rate and rhythm of your heartbeat, and the strength of the electrical signals that control your heartbeat. Some tests also take pictures of your heart at rest and when it's working hard.
What your results mean
Reference ranges vary by laboratory and by your age and sex. MedlinePlus does not publish a single normal range for this test — always read your result against the range printed on your own lab report and discuss it with your provider.
