Dobutamine Stress Echocardiogram (DSE)
What is it?
A Dobutamine Stress Echocardiogram (DSE) is performed to assess your heart’s function and structures both at rest and under stress. A Dobutamine Stress Echocardiogram is a variant of Exercise Stress Echocardiography and is suitable for patients who are unable to exercise on a Treadmill. The investigation combines an:
- Electrocardiogram (ECG)
- Intravenous infusion of the drug Dobutamine
What special preparation is required prior to a Dobutamine Stress Echocardiogram?
If you are taking Beta Blockers, your Cardiologist may ask you to stop taking this medication on the day of the test. This will be confirmed prior to your procedure.
Women are asked to wear a skirt or pants to enable the ECG electrodes and the Echocardiogram transducer to be placed on the chest.
What will occur during the Dobutamine Stress Echocardiogram?
The investigation will take place with you lying on your side and on your back. Initially an intravenous cannula will be inserted into a vein in your arm, your Blood Pressure recorded, ECG leads placed on your chest and an Echocardiogram performed.
Dobutamine will be administered intravenously and a second Echocardiogram will be performed. During the infusion of Dobutamine you may experience symptoms such as headache, flushing or an increased, (thumping) heart rate. Your ECG, Blood Pressure and symptom will be monitored during the investigation and you will be asked to breathe out and hold your breath briefly several times during the Echocardiogram. Upon completion of the investigation your intravenous cannula will be removed.
Complications are rare during Dobutamine Stress Echocardiography. Heart attack or abnormal heart rhythms may occur rarely. The risk of death is about 1 in 10,000.
How long will the Dobutamine Stress Echocardiogram take?
Approximately one hour.
What will happen after?
You will receive feedback from the Cardiologist conducting your test during and after the test and a full report will be sent to your referring Doctor on the same day. Drinking water and a towel will be provided and you will be asked to rest for about ten minutes before leaving our Clinic.
