WHAT DOES AN EXERCISE TOLERANCE TEST ASSESS?
The exercise tolerance test allows to indirectly assess whether there is a lack of oxygen in the arteries. Indeed, through the ECG we can see where there are signs of the suffering of the heart due to blocked coronary artery disease.
There could also be a fluctuation during the exercise test with hypertension or also hypotension and some arrhythmias can be triggered like atrial fibrillation, flutter or SVT.
If we notice some PVCs or ventricular ectopics affecting your heartbeat during the exercise stress test then this could be
or it could be a sign of underlying obstructed arteries
CONTRAINDICATIONS TO THE EXERCISE STRESS TEST
Contraindications to the exercise test are severe aortic valve stenosis or recent heart failure or unstable angina which means chest pain also at rest, not only on exertion.
We stop the exercise test if the patient develops changes in the electrocardiogram or if they have episodes of chest pain.
ARE THERE ALTERNATIVES TO THE EXERCISE TOLERANCE TEST?
Of course there are alternatives also to the exercise test, such as Dobutamine stress test, mainly used for people who cannot exercise, during which medication is injected into your vein which makes the heart pump faster and therefore it allows the visualisation of the walls of the heart to see whether or not they contract well and it also monitors chest pain and other symptoms.
