Q. Define Eye Balling?
Ans.
Two-dimensional echocardiography provides a good visual perception of cardiac functions. With experience, the echocardiologist learns to perceive and approximate the LV ejection fraction visually. This is called Eye Balling. Whenever this method is used, a value to the nearest 10 per cent or a range (e.g. 40-50 per cent) should be given since estimate can never be precise.
