Scared- Bad PVC's

I am so sick of getting PVC;s at nighttime.  They are really scaring me.  I have had a work up earlier this year (echo, stress test, ekgs, bloodwork, event monitor) and everything was normal.  I always get extra beats and stuff, many per day but sometimes at night they get very bad.  The other night, I had a migraine (so Im wondering if they could have been bad due to stress/ pain) and as soon as I laid flat my heart started fluttering and flip flopping like crazy. I got up and called a friend who calmed me down, bu then I got really cold and started shaking. I was scared to try and go to sleep so I didnt get much rest that night.  Does anyone else get this, and should I be concerned?  Everytime I call my cardiologist about these, they basically blow me off because Im young.  They tell me its "normal": (whatever) and to try and take Magnesium supplements.

Bria--I get them often.  They are scary but are really not serious.         Often, when i wake up w a headache i know it's gonna be a very bad day.      Esp when i lay on my stomach at nite--often it takes my breath away.  Does THIS ever happen to you?

  What helps me is Valium & magnesium yablets (500 mg....once or twice/day.  Get back--Robert
