What is an exercise test?
The exercise stress test is a sequence of cardiac ultrasound scans performed at different levels of exertion and is aimed mainly at performance athletes but also amateur athletes who have a very active life.
Specifically, the cardiologist performs echocardiograms at rest, at intermediate effort, at maximum effort and in recovery, so that, during the test, the changes in heart muscle movement and electrical changes that occur during exercise are monitored by comparing the stages of effort mentioned above.
If the doctor notices the existence of movement abnormalities at maximum effort reached by the patient, compared to their absence at rest, this implies the presence of myocardial ischemia through coronary artery infusion.
The existence of electrical changes has the same significance, and the association between movement and electrical changes increases the likelihood of the existence of an infundibular disease of the coronary artery or arteries serving the affected territories. Stress testing is also necessary in the evaluation of the behavior of cardiac valves during exercise. This helps in making an operative decision.
