Exercise Tolerance Test at our London Cardiology Clinic
An Exercise Tolerance Test is a non-invasive test used to evaluate how your heart responds when it is working harder than usual. During the test, your heart’s electrical activity (ECG), heart rate and blood pressure are monitored while you walk on a treadmill.
By assessing your heart under stress, this test can identify changes that may not be present when you are at rest, helping your doctor make a more accurate diagnosis.
At St John & St Elizabeth Hospital, our private cardiology service in London provides consultant-led care with access to modern imaging technology and a dedicated endoscopy suite. Patients benefit from a comfortable private ward environment, expert monitoring throughout the procedure, and rapid access to follow-up care.
Our cardiologists and specialist teams are committed to delivering safe, high-quality cardiac diagnostics, helping you gain clarity and reassurance about your heart health.

Your doctor may recommend an exercise tolerance test in London to:
- Investigate symptoms such as chest pain, breathlessness, palpitations or dizziness
- Assess how well blood is flowing to your heart during exercise
