Stress Testing is designed to give you information about the health of the heart and help diagnose rhythm problems, artery blockage and prior damage. During stress testing, we conduct an electrocardiogram (ECG) while the patient exercises on the treadmill. The exercise difficulty and duration increase during the test so that we can obtain more information about how the heart performs. In some cases, we may combine imaging of the heart with the ECG to gain additional information (See Nuclear Cardiology). We also provide non-exercise protocols for patients who cannot adequately walk on a treadmill.
