high risk due to pre-e 1st pregnancy. doc wants to do an EKG?

Kaitlyn
Any elses dr have them get an EKG because of a history of pre-eclampsia? What was the reason? I didnt speak with the dr, on the receptionist because it was over the phone and she basically said it was just to make sure everything is okay. 
what are they looking for? I wont see my doc again until after i get it done.
