Low Blood Pressure/ Low heart rate

I am a 43 yr old women, 5' 7" and 150lbs, I have low blood pressure 80/63 and a heart rate of around 45 BPM (resting), I eaisly feel faint, ringing in ears, dizzy, nausous, heavy sweating and just feel tired and sleepy alot.  my question is is this normal?  I am not an althlete, I do exercise regularly but nothing strenous by any means.  I am waiting on blood test results, but my dr is concerned about the EKG I had yesterday and thinks these may be related.  I have always had low BP...and have had episodes of feeling faint in the past.....but recently, it seems to happen after I eat, and is very scary.....any information would be great!

Thanks

are you seeing a cardiologist?   please make an appt. if you are not already.  please let us know how it all goes.   my daughter was feeling tired, looking pale, and slept alot.   i just thought it was her age and activity level (she was 19 at the time) and after a routine cardio visit we found out she had cardiomyopathy...   so i have learned that when you don't feel right, get it checked.
