Treadmill Stress Testing

Board-certified in cardiovascular diseases, Dr. Suresh Gadasalli currently serves as director of The Healthy Heart Center in Odessa, Texas. Dr. Suresh Gadasalli offers the full range of cardiovascular diagnostic testing. He performs stress tests to determine how much stress a patient’s heart can handle before abnormalities occur.

Also called an exercise stress test, a treadmill stress test involves monitoring a patient’s blood pressure, breathing, heart rate, and heart rhythm while he or she walks on a treadmill or pedals a stationary bicycle. This test is performed to determine whether a patient has coronary artery disease, which prevents proper blood flow, or heart arrhythmias, which increase a patient’s risk of stroke or heart failure.

Prior to the test, the patient will be hooked up to an electrocardiograph monitor, which measures the heart’s electrical activity. Then, his or her resting heart rate and blood pressure are checked. Next, the patient is asked to walk on the treadmill or ride the stationary bike at increasing levels of difficulty while the heart and breathing are monitored. Typical exercise times are no more than 12 minutes, and patients can stop at any time if they develop pain, dizziness, or other unusual symptoms.

If the test results show signs of cardiac abnormalities, the physician will order more tests to determine the appropriate course of treatment.
