Dobutamine Echocardiogram 

Dobutamine Echocardiogram

A Stress/Dobutamine Echocardiogram is a specialised test used to assess how your heart functions under stress when you are unable to exercise. Instead of physical activity, a medication called dobutamine is administered to simulate the effects of exercise by increasing your heart rate and the strength of your heart’s contractions. This allows our cardiologist to evaluate blood flow to the heart muscle and detect areas with reduced circulation or abnormal function. 

It is commonly used to: 

  • Diagnose coronary artery disease. 
  • Assess heart valve function. 
  • Evaluate heart muscle performance after a heart attack or assess cardiac fitness prior to surgery.

Patient Preparation

  • Fasting: Do not eat or drink for 2 hours before your appointment. You may sip water if needed. A small snack is alright for diabetic patients. 
  • Medications: Do not stop any medication without medical advice. 
  • Clothing: Wear loose, comfortable clothing. You will be lying on your side for an extended period. 
  • Driving: It is recommended to arrange transport home, as you may feel tired or light-headed after the test. 
  • Consent & Questions: You will be asked to sign a consent form before the test. Feel free to ask any questions—your comfort and understanding are important to us. 

What to Expect During the Test

  • You will lie on your left side while ultrasound images of your heart are taken before, during, and after the dobutamine infusion. 
  • Electrodes will be placed on your chest to monitor your heart rhythm, and a small IV line will be inserted into your arm for the medication. 
  • Your heart rate will be gradually increased to a target level, and the test will be stopped if any concerning symptoms arise. 
  • The entire procedure takes 50–60 minutes, with the medication infusion lasting around 20 minutes.
