An exercise tolerance test (ETT) is the same as an electrocardiogram (ECG) but recorded while you are exercising.
This test assesses how well your heart works when you are doing something active. During exercise, your heart needs more blood and oxygen and is therefore working harder.
The test will show if there is a lack of blood through the arteries that supply the heart.
An exercise tolerance test usually takes between 10-15 minutes and is far more valuable if you try to walk for as long as possible.
Before you come you will be asked to wear appropriate clothing and footwear. Ensure you don’t eat any big or heavy meals before taking this test.
Small sticky electrode pads will be placed onto your chest which are connected to wires. A physiologist will take your blood pressure at the start of the test, before asking you to cycle on an exercise bike. You will be asked to continue cycling until enough information has been obtained.
Your results will be sent to you or the person who referred you, and your consultant (if available) will be able to give you an informal result straight after your test.
• Dizziness or light headedness
• Low blood pressure
• Nausea or vomiting
• Pain or pressure in the chest, jaw, neck, or left arm or between the shoulder blades
