Stress Testing

Back to Tests and Procedures

What is a Stress Test?

This is a test that we use to see how the heart responds to exercise.  This test lets us see signs and symptoms of heart disease.  We also use this test to determine how well your heart medicines are working.

Types of Stress Tests

  • Routine exercise treadmill tests, performed by walking on a treadmill at different speeds while being monitored.
     
  • Most stress testing is now done as a nuclear stress test, where a small dose of radio-isotope is injected and the heart is scanned at rest and following exercise in order to determine any problems in the blood supply to different regions of the heart.
     
  • Pharmacologic nuclear stress testing involves the administration of a medicine to make the heart work harder than it does at rest.  This is a helpful test for those who cannot walk the treadmill effectively.
     
  • Stress Echo tests are also occasionally done utilizing echo to look at the heart muscle at rest, and after stress.  This can either be done incorporating a treadmill, or pharmacologically (using medication)
