The Test

  • We will ask you to sign a consent form giving us the go-ahead to do the test.
  • We will prepare the skin on your chest where the electrodes will be placed with a coarse lotion. We may have to shave some hair from the chests of male patients. Doing so ensures the electrodes make good contact with the chest to accurately monitor your heart’s rhythm.
  • You will then walk on the treadmill. An exercise physiologist will watch the monitor for any changes that may suggest heart disease or rhythm problems.
  • We will check your blood pressure often during the test.
  • The test will take about 30 minutes.
