What is meant by "EF=60%" (part of an echo-cardiogram test)?
463954
it stands for ejection fraction it is the portion of blood in  your heart that is pushed out with every squeeze 55% and up is normal

i think it would be f-critical times Degress fredom alpha.  but i am not 100%.  i'm going with that b/c i dont think there is addition in that function.  the real question is how much turkey is there in the turkey test?

The top number is the systolic rate,the bottom number is the diastolic rate.\n\nSystolic pressure (the higher,first #) measures the force that the blood exerts on the artery walls as the heart contracts to pump the blood.\n\nDiastolic pressure (the lower second #) is the measurement of force as the heart relaxes to allow blood to flow to the heart.

Alex is right, but what you mean is oxygen saturation of the blood.  This tells you how much oxygen is saturated in the hemoglobin of the blood to transport through the body.  Ideal, like Alex said is 95%-100%.

Yes.  It is 80% or a B

My honest feeling is the BP readings taken are not correct. Such high and low changes are next to impossible. You need to tak him to a cardiologist for evaluating the position and treating him. Blood Pressure - high or low - is termed as silent killer. Please see the doctor without delay. \n\nNow a short note from Wikipedia about BP for your inforamtion -\n\nBlood pressure is the pressure exerted by the blood at right angles to the walls of the blood vessels. Unless indicated otherwise, blood pressure refers to systemic arterial blood pressure, i.e., the pressure in the large arteries delivering blood to body parts other than the lungs, such as the brachial artery (in the arm). The pressure of the blood in other vessels is lower than the arterial pressure. Blood pressure values are universally stated in millimetres of mercury (mmHg). The systolic pressure is defined as the peak pressure in the arteries during the cardiac cycle; the diastolic pressure is the lowest pressure (at the resting phase of the cardiac cycle). The mean arterial pressure and pulse pressure are other important quantities.\n\nTypical values for a resting, healthy adult human are approximately 120 mmHg systolic and 80 mmHg diastolic (written as 120/80 mmHg), with large individual variations. These measures of blood pressure are not static, but undergo natural variations from one heartbeat to another or throughout the day (in a circadian rhythm); they also change in response to stress, nutritional factors, drugs, or disease-

I believe your mother has been diagnosed with a heart murmur, not an echo.  An echo (or echocardiogram) is sometimes used to determine if a murmur is a significant problem.  Depending on the timing, length, and severity of the murmur, plus extra or skipped beats, this may or may not be a serious problem.  Only a through physical exam, plus diagnostic studies mentioned above, can make that determination.  Hope this was helpful!

your O2 saturation rate is the % of oxygenated blood running through your body. Normal is around 98% to 99%

BP refers to "Basis Points".  One basis point is equivalent to 1% of 1% or 0.0001.  In the example provided the reference is to 8 or 9/100th of 1%.

any increase in ef is usually good.It means your heart is pumping more efficiently. The main thing you should worry about is why(leaky heart valve, virus, alcohol consumption) your heart was dilated in the first place and try to fix it. The aortic size is harder to evaluate the place I work at now that would be large but other places use different measurements and that could be normal. Go to www.seemyheart.org its a web site by the American society of Echocardiography for patients to understand there results

This isn't really a question, but a test result. What is shows is a heart that has decresed blood supply that causes changes in the EKG, which is the electrical output of your heart with exertion. \n\nThe marks on an EKG are labelled P-QRS-T. The P is the contraction of the upper chambers of your heart, the QRS is the contraction of the larger lower chambers of the heart, and the T is the relaxation phase of those lower chambers, called the ventricles. The lead numbers and letters represent directions through the heart, and which ones have changes show the cardiologist what areas have decreased blood supply. "ST" changes are the place in the PQRST the hungry muscle shows up. "Ischemia" means dimininshed blood supply.\n\nThis usually means the coronary arteries which feed the heart blood have a blockage or other restriction of flow, from clots, build up of plaque or other damage. \n\nMore tests are needed to determine what kind of problem exists. A nuclear scan would show whether muscle has already been permanently damaged  or if it is possibly reversible. The "gold standard" would be a heart catherteriztion to map the exact problem, and even fix it with a balloon or by placing a stent.\n\nA test result like this one indicates a need for more follow up and whoever has this needs to promptly follow up with a cardiologist, preferably an interventional one. It's not a time to panic but to take necessary action.\n\nHope that answers some of your question, but this should be discussed with the doctor until you are satisfied with what it means.

Look just below the table; it should have a key there, saying what % of positivity each symbol refers to.  I do not have a Bergey's here at home; we have them in the lab.\n\nAFAICR, each symbol refers to a % of that genus (or species??) which is positive for each biochemical test.  For example, D means most ... something like 90% or more, while d means a minority are positive, say 10% or less.  It is hard to remember, here at home.\n\nAs I said, the book tells you (AFAICR).

Sorry for my previous answer, I was mistaken. \nI believe answer is B. A is correct, but I don't think it is why it affect target tissue for loger time. I don't think C is correct, but it could be. D is certainly wrong and E too. I haven't seen this in a while. Sorry I couldn't be more help.
