A Dobutamine Echo is used to help the physician diagnose any potential structural or functional cardiac abnormalities. The test is commonly requested for coronary disease.
Before showing up to the office for the test:
- Do not apply any oils or lotions to the skin 24 hrs before the test
- Make sure you withhold any medications as directed
- Bring all medications you are taking, or an up to date prepared list of all medications you are taking
- Do not eat a heavy meal before the test
During the test:
- You will be hooked up to a 12 lead heart monitoring system which will monitor your heart rhythm and rate throughout the duration of your stress test
- You will also be hooked up to an IV line used to administer medications during your test
- A baseline electrocardiogram and blood pressure will be taken at the beginning of your test
- A physician will briefly asses you before the test to ensure your safety
- A small amount of special sound conductive gel will be applied to your chest and an ultrasound of your heart will be done (the gel may have a cool feeling to the skin)
- A special medication called Dobutamine will be given to you through the IV line. This medication is meant to do the same function as if you were on a treadmill speeding up your heart rate.
- When the required heart rate is reached, the infusion of Dobutamine will be stopped and another ultrasound will be performed on your heart while it’s beating quickly
- You will then be monitored for a period of time until your heart rate return to a safe rate
If at any time during the test you feel unwell, please let the Ultrasound Technician, Cardiology Technologist or Nurse performing your test know. Symptoms may include Chest Pain or Tightness, Shortness of Breath, Dizziness.
