Regular Stress Test or Stress Echo

  • Preparation: Wear comfortable clothes and appropriate shoes for walking on the treadmill.

  • Purpose: This test measures your physical condition and heart function. You will be asked to walk on a treadmill that gradually increases in speed every three minutes until you have reached your target heart rate or if you indicate you can't walk anymore. For a stress echo you will have ultrasound pictures of your heart taken before you walk on the treadmill and within a minute after completing the treadmill portion.

 

Nuclear Stress Test

  • Preparation: Wear comfortable clothes and appropriate shoes for walking on the treadmill.

In this test you will be given an intravenous injection of a radioisotope. Next, you will have pictures of your heart taken under a special camera for about 30 minutes. Following the first set of pictures you will be asked to walk on the treadmill and you will be injected with a radioisotope just prior to the end of the test. Another set of pictures will be taken 10-15 minutes later.
