A stress test is a diagnostic examination that evaluates heart function during physical exercise.
It is typically performed by walking or running on a treadmill or cycling on an exercise bike, while the patient is connected to electrodes that record the electrocardiogram. As the intensity of the exercise gradually increases, the doctor monitors how the heart responds to the physical stress.
The main reason for conducting a stress test is to detect possible signs of coronary artery disease, problems with the heart’s blood supply. It can also be used to assess physical fitness, investigate symptoms such as chest pain or shortness of breath during exertion, or to monitor the heart’s condition after treatment or surgery.
The test is painless and safe when conducted under medical supervision, and it provides valuable information about heart health. It is a simple yet essential examination that helps in the early diagnosis of cardiac conditions and supports informed decision-making regarding the patient’s health.
