UNDERSTANDING ECHOCARDIOGRAM AND CARDIAC CATHETERIZATION - QUIZ QUESTIONS


Scenario: Ron is transferred to CCU. The cardiologist in CCU (Coronary Care Unit)
ordered an echocardiogram and cardiac catheterization.

An echocardiogram is performed using ultrasound. It can provide information such
as heart valve disease, blood clots, and more. The ejection fraction (the amount of
blood ejected from the left ventricle each time the heart contracts) is also measured.
There are different types of echocardiograms.

The one described above is the standard kind. The Transesophageal Echocardiogram
 (TEE) is done using the esophageal approach. Dopamine stress echocardiogram is yet
 another type which may be done.

Cardiac catheterization is a valuable diagnostic tool. It is performed in a special
 laboratory. A small catheter  is inserted into the heart via the arm or groin. It is
an invasive procedure and is done under fluroscopy. Contrast dye may be used.
Sedation is given prior. The vital signs and oxygen saturation are documented
before, during, and after. A consent is needed from patient or guardian.

The test helps to determine conditions such as obstruction to blood flow, heart
 pressures, and more.

Quiz questions

1. What is the purpose of the echocardiogram?
2.What are the different types of echocardiograms?
3. How is a cardiac catheterization performed?
4. What can be learnt from cardiac catheterization?
