Resting HR 120-160 found in notes I also have Left ventricular ejection fraction 52% been passing out a lot should I be worried/is this the cause?

Unfortunately yes: You could be having a dangerous heart rhythm, leading to the passing out. The ejection fraction of 52% is still within the normal range; however, you are tachycardic at baseline, and the fast heart rate may overestimate your true ejection fraction as well as lead to heart damage. If you pass out again, I recommend calling 911, otherwise, see cardiologist ASAP. ...Read more

I had a hidascan scan done my ejection fraction was 10%... Would that recommend surgery?

I had a hidascan scan done my ejection fraction was 10%... Would that recommend surgery?

HIDA scan: measures function of gallbladder. Normal EF is >40%. A low ejection fraction is one of the pieces of information used in making surgery decision. You should discuss this with your surgeon. Thanks for trusting HealthTap! ...Read more

Is there any study that shows using Half & Half in a HIDA scan is as accurate as CCK? My ejection fraction was 31%

Yes.: Here is the link for that study: http://jnm.snmjournals.org/content/43/12/1603.full It shows that there is wide variability in the ejection fraction measured when half and half, instead of CCK, is used in a HIDA scan. However, the study concludes that both methods are acceptable. Hope that helps! ...Read more

Why did they stop the HIDA scan (without CCK) before testing the ejection fraction? Can't that be a problem of its own?

Why did they stop the HIDA scan (without CCK) before testing the ejection fraction? Can't that be a problem of its own?

Yes: Did they have CCk? It is not generally available. Have to substitute standardized fatty meal. Otherwise results are equivocal. Sometimes clinicians will not use CCK if suspect acute obstruction of biliary system or if no activity is in gall bladder. Should ask institiution performing the test for explanation. CCK or fatty meal substitute gives indication of gall bladder function. ...Read more

Hida scan results ejection fraction rates 30% at 30minutes 46% at 45 minutes and 50% at 60 minutes. I am very symptomatic with eating, recorecommendat?

Depends on how the : Gallbladder ejection fraction was performed. If the gallbladder contraction drug (cck or sincalide) was administered at a dose of 0.02 micrograms/kilogram over 1 hour, then a normal gallbladder ejection fraction would be greater than or equal to 38% at one hour. Unfortunately, there is variability in the % depending on exactly how it is performed. Check with your doctor for what normal is. ...Read more

Do I have to fast when having a hipa scan with gallbladder ejection fraction?

Yes: Before having a 99mtc-hida scan to evaluate gallbladder ejection fraction ( function) or patency of intra or extra biliary tree, it is always recommanded to fast at least4-6 hours, in order to better evaluate the gallbladder contraction. ...Read more

Hi doctors, was just wondering what is a normal ejection fraction %age on a hida scan? What's good, what's bad?

Hi doctors, was just wondering what is a normal ejection fraction %age on a hida scan? What's good, what's bad?

Greater than 35%: Normal ejection fraction in adults usually is greater than 35%. Significance of ejection fractions has to be compared to clinical signs and symptoms of patient. ...Read more

What does ejection fraction means? I'm having a hida scan tomorrow because i'v been diagnosed w/a gallbladder sludge

Ejection fraction is: A measure of how effectively the gallbladder releases bile when it contracts. During a hida scan, the gallbladder accumulates the radioactive substance. Another medication is then given (cck) which stimulates the gallbladder to contract. A special camera measures how well the gallbladder empties. This is reported as a percentage. If abnormal, this may be a source of pain without gallstones. ...Read more
