Absolutely not. This must be a mistake.
Hi Joan. I always opt for a good old echo cardiogram. Non-invasive, no radiation, no injections, and I think it gives the clearest picture of ejection fraction and left ventricle size and performance of the entire heart. It takes you about 20 minutes to see exactly how your heart is performing. Doesn't show you the perfusion directly, but you can pretty well determine by how well the muscle is performing if it is getting adequate perfusion. I think they even have 3D now. I would like to see that one.
I googled it and it says that 55 ot 70 is normal. It also says "A LVEF of 65, for example, means that 65% of the total amount of blood in the left ventricle is pumped out with each heartbeat".
I seem to remember that I was in the 40's after my heart attack, but was about 60 at the last check.
When people go into heart failure, their left ventricle is so atrophied that it just balloons out with every heart beat and doesn't push the blood out of the heart.
But I don't think that you can get up to 98%. You should have another test.
Thank you for your response, but the 98% was definitely not my O2 sat.
Is this possibly your oxygene saturation? This is normal to measure during stress test. If so, your result is well within normal limits.
