You will be asked to remove any clothing covering the upper half of your body and be offered a hospital gown to cover yourself up during the test. 3 electrodes will be attached to your chest and will be used to monitor the heart rhythm during the test.
Lubricating gel will then be applied to your chest and an ultrasound probe will be used to obtain the pictures. The procedure is not painful but you will feel some pressure on the chest as the probe is pressed down to obtain high quality pictures.
The whole procedure takes approximately 30 minutes and you can go home immediately afterwards. The procedure is safe without the requirement of the administration of any medication. There is no specific preparation required prior to a TTE.
