1st degree av block?? anyone help please......

[jgoodwin]

I have been diagnosed with 1st degree av block and my heart is not filling up with blood fast enough.(Which is why I guess, I get light headed and dizzy when I do any kind of assertion or anything)   I am 33 year old female. very healthy, I do not drink, smoke, very rarely drink caffeine.  I always stay fatigued and very tired, but am a mother of 3 and work 40-50 hours a week.  My mother had a heart attack at 58 and survived.  She had a 99 % blockage in an artery and now has a stint.  When I was pregnant with my 4 year old.  My mitral valve was not closing in my heart.  I have had an echo done about 2 years ago and it showed my mitral valve to be closing.  Any time I assert my self, (cleaning , sweeping, walking too fast for about 50 foot steps,) I get lite headed, dizzy and short of breath.  I have to sit down so I don't pass out.  We found this av block a week and a half ago and am running blood work, a full work up.  Can I go like this for ever or will I need a pacemaker?  Can medicine fix this or any help on this matter is greatly appreciated.  Also, do you think their could be some damage to my mitral valve from my pregnancy?  I do even have some sharp piercing pains periodicaly,, racing heart beat, pounding heart beat, even some flutters or quivers and sometimes it feels like a worm is crawling through???     Thanks  Jana........
