Please do not worry about this test as it is done frequently and non invasive. You can have it done in the physician's office or in the hospital setting.
The echo can show size of the chambers of the heart, including the dimension or volume of the cavity and the thickness of the walls. The appearance of the walls may also help identify certain types of heart disease that predominantly involve the heart muscle. In patients with long standing hypertension or high blood pressure, the test can determine the thickness and "stiffness" of heart walls.
It can also diagonsis other heart functions such as the punping function of your heart chambers.
Please do not worry as like many tests they are done to rule out the worst scenario to be on the safe side.
I hope this explains it a bit for you and I promise it is painless but I do recognize that anytime we are scheduled for tests it is a trigger for anxiety to set in.
Take care of you.
