Hi Linda. Thanks for the reply. I learned a lot from the link you put in there. Yes, because of a LBB blockage my heart would not get the signal to beat at the same as the right side. The beat was off and very slow on that left side. Not pumping much blood out from that side either. I had two cardiac MRI's in Boston at Brighams and Womans hospital. Yes I was getting dizzy a lot. I'm feeling a little less tired as I used to get and no dizziness 9 days out.
