What Stress Tests Can Reveal About Heart Function

Doctor Monitoring The Heart-Rate Of Patient On A Treadmill

Cardiologists often recommend stress tests to check for the possibility of cardiovascular conditions such as coronary heart disease and abnormal heart rhythms. These tests inform the cardiologist how much stress your heart can handle before a problem, such as a drop in blood flow, develops. Stress tests are also helpful for determining the efficacy of heart medications and any procedures you may have had. There are three different stress tests that your cardiologist could request, which are listed below.

Exercise Treadmill Stress Test
If your mobility is unimpaired and your electrocardiogram (EKG) is normal, your cardiologist will likely request an exercise treadmill stress test. The technician attaches electrodes to monitor your heart activity while you walk on a treadmill. Periodically, the technician asks you to walk faster or at an incline. Promptly inform the technician if you experience any symptoms, such as dizziness or chest pain. The results of this test help your doctor determine a safe exercise program for you and/or diagnose cardiovascular problems.

Exercise Nuclear Stress Test
Your cardiologist might request a nuclear stress test in order to assess the circulation of blood through potentially damaged areas of the heart. The results can also tell your doctor how well your heart pumps blood and whether you have an enlarged heart. You’ll exercise on a treadmill while being monitored, and a technician will inject a contrast dye. A scanner then produces images of your heart. After resting for several hours, more images are taken.

Chemical Exercise Nuclear Stress Test
If you’re unable to exercise because of certain medical conditions, the cardiologist will recommend a chemical exercise nuclear stress test. This is similar to an exercise nuclear stress test, except a medication is used to mimic the effects of exercise. During the test, you’ll receive a contrast dye and have images taken. This test reveals the same information as an exercise nuclear stress test; the cardiologist can assess blood circulation and possible areas of damage.
