I am 28 weeks now and started experiencing heart palpatations in the 2nd trimester. My doctor is a little concerned but said it is also normal. I get the palpatations and feel real short of breath. It's not constant, and comes and goes. I'm cosidered a high risk preg, so my OB is sending me to a specialist. I'll try to keep you posted.

I haven't paid atention to myself personally...but I've read that it's normal for heartrate to increase to compensate for the increase in blood volume...how high are you talking? Normal resting heartrate is 60-100 beats per minute.
