Test d'effort (épreuve d'effort) in Paris, under medical supervision

It carries a well-established safety profile because it takes place under continuous medical supervision, with a team ready to intervene at any moment. The effort is adapted to your capacity and increased gradually in stages, and it's stopped immediately at the first abnormal sign: chest pain, an abnormal ECG change, an inappropriate blood pressure response, or significant fatigue. This close monitoring is precisely what makes it safe to deliberately push the heart under exertion in a way that reveals problems a resting ECG cannot. Beforehand, the cardiologist reviews your history to confirm it's appropriate for you.

Its main use is detecting coronary artery narrowing, since reduced blood flow to the heart muscle often shows up on the ECG only during exertion. It also assesses exercise tolerance, looks for rhythm disorders triggered by physical effort, and can check whether a treatment for a known coronary or rhythm condition is working. The cardiologist interprets the ECG changes, blood pressure response and any symptoms together, rather than any single measurement in isolation, to build a complete picture of how your heart copes with exertion.

About 30 minutes in total, including preparation, the effort itself and recovery. Fitting the electrodes and cuff takes only a few minutes; the effort phase, cycling or walking with intensity increasing in stages, typically lasts 10 to 15 minutes depending on how quickly you reach the target level. A short recovery period follows, during which your heart is still monitored as it returns to baseline. Planning for roughly 30 minutes covers the whole appointment comfortably.

Mostly practical: wear comfortable sportswear and trainers you can move freely in, and avoid a heavy meal in the two hours beforehand, since a full stomach can affect comfort during exertion. Don't change any regular medication on your own; if you're unsure whether a treatment should be paused, ask your cardiologist in advance, since some heart medications can affect interpretation. Bring your previous cardiology results if you have them. Arriving rested and hydrated helps you perform the effort comfortably.

Not beyond what's reasonable for you. The effort is progressive, meaning intensity increases gradually in stages rather than starting hard, adapted to your fitness and your reason for testing. The cardiologist and team watch your ECG, blood pressure and how you feel throughout, and the test stops as soon as a target is reached or at the first sign continuing wouldn't be appropriate. The goal is a clear answer about your heart, not a fitness challenge.

It's a sensible step before taking up or stepping up sport, particularly after 40, after a long break, or with cardiovascular risk factors such as high blood pressure, high cholesterol, diabetes or a family history. It complements the consultation and resting ECG by showing directly how your heart responds to exertion, which a resting test alone can't always predict. For an ambitious goal (a half-marathon, a trail run, returning to intense training) it gives you a safer, evidence-based starting point rather than guessing how your heart will cope.

Yes, that's one of its main purposes. A resting ECG records electrical activity for a few seconds while you're still, and some problems, particularly coronary artery narrowing and certain rhythm disorders, only reveal themselves when the heart works harder. This test deliberately increases the demand on your heart in a controlled, progressive, supervised way, so the cardiologist can see changes on the ECG, in blood pressure, or in symptoms that simply wouldn't appear at rest, which is why a normal resting ECG doesn't always rule out a coronary problem.

They look at the heart in different ways. This test records how your ECG, blood pressure and symptoms respond as controlled effort increases, particularly good at revealing coronary artery narrowing and exertional rhythm disorders. An echocardiogram is an ultrasound, usually at rest, showing the heart's structure: the chambers, the muscle, the valves. The cardiologist may combine both when a fuller picture is needed. For most patients, though, this test is chosen specifically to see how the heart performs under exertion, not at rest.

It's not appropriate for everyone at every moment, which is why the cardiologist reviews your history before booking. Certain acute conditions, uncontrolled symptoms, or specific heart conditions may mean postponing it or choosing another assessment. If you've had recent chest pain at rest, a recent cardiac event, or any symptom that feels acute and severe, tell the secretariat when you book so the team can advise on timing. In a genuine emergency, such as intense, lasting chest pain or fainting, call 15 (SAMU) or 112 rather than waiting for a scheduled test.

A prescription from your doctor is generally required to carry out complementary examinations. If in doubt, our secretariat is available to advise you.

Use the online booking button on this page, or call the secretariat. Mention your reason (exertional chest pain, breathlessness, or a check before resuming sport) so we plan enough time and confirm the test suits your situation. Wear comfortable sportswear and trainers, avoid a heavy meal beforehand, and bring your previous cardiology results and medication list. New patients are welcome. If you have symptoms at rest, such as lasting chest pain, treat it as an emergency and call 15 (SAMU) or 112 rather than booking a routine test.
