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

No it is not normal, but do not worry they will have some good answer and solution for you I am positive about that .You are not overweight and that is great !You are high enough for the 150lbs
Also: do you drink coffee? I think you should if you don’t.
Best wishes to find the answer.
