What is it?
An exercise stress test involves walking on a treadmill at gradually increasing speed and incline while ECG and blood pressure are continuously monitored. It helps assess how the heart responds to increased workload.
An examination is carried out beforehand to assess whether the test is suitable. A doctor and health staff monitor you throughout; the test is stopped in case of chest pain, marked fatigue, dizziness or rhythm changes.
The test may be used to investigate coronary artery disease, determine exercise capacity and examine some rhythm problems. Interpretation depends on your symptoms and risk factors; whether further investigation is needed is agreed after discussing the results together.
Who is it assessed for?
- Those with chest pain or breathlessness on exertion
- Those who need additional information for cardiovascular risk assessment
- People with known heart disease whose exercise capacity is to be assessed
- Those advised by their doctor to be tested before starting intensive exercise
