A stress echocardiogram is done to assess the blood flow to the heart and show any blockages in the blood vessels that supply it. It can also show problems with the heart muscle and narrowing or leakages of the heart valves. An echocardiogram done at rest will not always show if the blood supply to the heart is normal.
First you will have an electrocardiogram (ECG) and an echocardiogram while you lie still. During the test you will be asked to exercise on an E-bike for 15-20 minutes to increase your heart rate and make your heart work harder. During this part of the test, you will have an ECG monitoring your heart rhythm and a blood pressure monitor. When your heart rate is fast enough, you will be asked to lie down and you will have an ultrasound scan of your heart.
The ECG and echocardiogram are not painful. Your doctor will discuss all the risks and benefits before you have a stress echocardiogram.
