A stress or exercise tolerance test is designed to provide information about coronary artery disease, cardiac arrhythmias, possible heart related chest pain, dizziness and shortness of breath.
The test investigates how well the heart functions when it is under pressure through exercise. During the course of exercise, the heart muscles require more oxygen and hence the heart has to pump more blood. The test can show if there is a reduction in blood supply in the arteries that supply the heart itself during exercise. If positive, the test can predict possible ischemia in the heart. It also helps doctors ascertain the mode and level of exercise appropriate for the patient.
If you are coming for the test, you are advised to bring loose clothing or clothing that is suitable for exercise as it will involve walking on a treadmill. Electrodes are attached to the chest and are connected to an ECG machine. They are used to monitor the heart rhythm / wave form and ensure your safety. Blood pressure is also monitored at regular intervals throughout the test. The test generally lasts about 30 minutes all together with up to 15 minutes on the treadmill.
The results are sent to the referring GP or Consultant within 24 hours.
