Cardiac Stress Testing
Cardiac stress testing is an important diagnostic and prognostic tool in the evaluation and management of patients with known or suspected coronary heart disease. While stress testing can be performed in a variety of ways, the most commonly used and widely available stress testing modalities are exercise electrocardiography (stress test; non-imaging) and exercise combined with imaging (stress echocardiography).
Cardiac Stress Test or GXT
During a Stress Test an exercise ECG measures your hearts electrical activity, blood pressure and heart rate while you exercise by walking on a treadmill. Cardiac Stress Testing is used in the diagnosis and treatment of patients with known or suspected cardiovascular disease.
Stress Echocardiography or Stress Echo
Stress Echo is similar to a Stress Test, except an echocardiogram (an ultrasound study of the heart) is performed before and after exercise. During the test an exercise electrocardiogram (ECG) records your heart's response to the stress of exercise. An exercise ECG measures your heart's electrical activity, blood pressure and heart rate while you exercise by walking on a treadmill.
