Exercise stress test Stress test
Walking on a treadmill or cycling while the ECG, blood pressure and symptoms are monitored.
What it can show
How the heart responds when it has to work harder, and whether symptoms appear on exertion.
What it cannot show
A normal result does not entirely exclude coronary disease, and some people cannot exercise long enough for a conclusion.
This is the half people skip. A normal result answers one question, not every question.
Tell the staff before you start
Chest pain in recent days · severe breathlessness · knee or hip problems limiting walking · current medication.
Also bring the full list of every medicine and supplement you take. Things bought without a prescription belong on that list too.
