Hello: I'm a mid-forties male. Two years ago I was given a physical exam by a GP which included an EKG. It showed LBBB. I just had another physical exam by the same doctor which included an EKG but this time it did not show any LBBB. The doctor said the LBBB is presently gone and that I have intermittent LBBB. Does that sound right? Could the machine have been mis-set either or both times? If it really is intermittent, I guess I can get it again next week, right? Why all this strange activity in my heart? Thank you. Mike To respond to me personally, please remove the "xyz" from my email address.
