Results
A cardiac blood pool scan shows how well your heart is pumping blood to the rest of your body.
Complete test results are usually available in 1 to 2 days. The most commonly reported value is the ejection fraction, which is the average amount of blood pumped out of the heart's left ventricle during each contraction.
| Normal: | The ejection fraction is 55% to 65%. |
|---|---|
The walls of the ventricles are contracting normally. | |
The chambers of the heart are not enlarged. | |
| Abnormal: | The ejection fraction is less than 55%. |
Parts of the heart muscle are not contracting normally. | |
A defect, such as an aneurysm, is present in the wall of the heart. | |
The heart valves do not close completely, allowing blood to flow in the wrong direction. | |
There are openings between the heart chambers, allowing blood to leak between the right and left heart chambers. | |
The chambers may be enlarged (cardiomyopathy). |
Many conditions can affect cardiac blood pool scan results. Your health professional will discuss any significant abnormal results with you in relation to your symptoms and medical history.
