Echo question ;-/

[Lilchic586]

Hi everyone, my question is about two recent echos I had gotten. The first one the doc just wanted to do it bc I had mentioned I was having paps and dizziness sometimes. It was done on June 12 and everything seemed normal and it said my ejection fraction was 66%. Now less then a month later on July 2nd I started feeling weird again so I went back to doc, they did second echo that day said everything was good and normal but when I looked at the results of the second one it said "overall left ventricular systolic function is low-normal with and Ef of 50%" and it also said "trace tricuspid regurgitation present" can someone please tell me what this means? And why would my Ef would go from 66% to 50% in less then a month and be told it's all normal? I do have anxiety, especially about my heart. I eat decent,28 years old. Former smoker, occasional drink. Moderate exercise, walking. Should I be worried and demand more tests? Please help. Thank you for taking the time to read this.

I'm not a health professional but have had lots of Echos and a great deal of heart problems.  EF is transient, I wouldn't worry about it unless you get huge swings in numbers.  For example, if I got a 50% EF rating, I'd be out celebrating.  
A lot depends on who is doing the test, and how skillful they are.  I don't worry much about EF numbers, but do pay attention to the wording.  For example, the word 'trace' means basically your heart is normal, no one has a perfectly performing heart.  Generally, procedure reports use the words Trace, Mild, Moderate, Moderate/Severe and Severe regarding valve function.  Trace means to me a normal heart.
Palps are very seldom a serious heart problem.  Given your age and anxiety over heart issues, I'd just relax, and enjoy being 28 years old!  Keep us informed.
