Stress Test

An exercise stress test, also known as a cardiac stress test or exercise electrocardiogram (ECG), is a diagnostic test that is used to evaluate the performance of the heart during physical activity. The test is typically done on a treadmill or stationary bike, and the patient is asked to gradually increase the intensity of their exercise while their heart rate, blood pressure, and ECG are monitored.
The test is used to diagnose conditions such as coronary artery disease, arrhythmias, and other heart-related issues. During the test, the physician will look for changes in the ECG pattern, abnormal heart rhythms, or chest discomfort that may indicate a problem with the heart. The test may also be used to evaluate the effectiveness of medications or treatments for heart conditions.
For arrhythmia purposes, a stress test can be used to rule out coronary artery disease as the cause of arrhythmia, induce certain arrhythmias, assess the response of certain arrhythmias to exercise, or to help with the screening and diagnosis of sudden cardiac death syndromes.

The exercise stress test is a non-invasive and relatively safe procedure, but it should only be performed under the supervision of a trained healthcare professional. It is important to follow any instructions provided by your doctor before the test, such as fasting or avoiding certain medications, to ensure accurate results. It is also important to come wearing appropriate clothes and shoes for exercise.
