How it is done?
A technician puts electrodes on your chest with adhesive patches and a gel that conducts electrical impulses. The wires from the electrodes are attached to the ECG, and electric activity from the electrodes is recorded.

You will have several resting ECGs before the actual testing begins. These initial tests are compared with the ECGs taken during exercise. Blood pressure is monitored throughout all of the tests.

You will begin riding a stationary bike or walking on a treadmill. The intensity of the exercise is gradually increased. You will continue exercising until you reach your target heart rate. The test should be stopped if one feels any of the following:

• Unsteady gait
• A drop in blood pressure
• Dizziness or fainting
• Skin that becomes cold and clammy and grayish in color
• Confusion
• Irregular heart beats
• Chest pain
