LVEF Question

Update...
I talked with my doctor last night and because EF measurement is not that precise he said not to worry. However, I've been having problems with breathing on and off lately. My friend noticed it seems to happen after my Herceptin treatments and lasts a few days. Each time it comes back it seems to get worse. He ordered a diagnostic echo immediately following my next treatment to see if there is any correlation to my symptoms.
