Changes in EF but still within normal range

I started having some heart palpitations, shortness of breath and dizziness and went to cardiologist for check up. Doctor did ecg, echo and stress test and said I have a very good heart. I Came home studied the reports and echo showed EF of 60%. And I compared It to the test I did last year where echo showed 66% at another doctor. Both reading were by m-mode. Does it mean that my EF is falling and therefore I started having the above symptoms?

There will always be some degree of intra- and inter-observer variability in the calculation of ejection fraction. The difference in your case is probably not clinically significant, especially since both values fall within normal range.
