I get them like 5 times a day, depending on my stress level. Sometimes I go weeks without skipped beats. It started 1.5 yrs ago.

I've been to the cardio already and he said I'm fine. They did all the tests, including holter (sp).

I'm 31, had a baby 21 months ago, don't smoke or drink.
It gets worse when I'm bending over to pick something up or when I'm yawning. Weird huh.

My actual question is: Does everybody get them or only people that have sick hearts?

it just feels like your heart skips a beat...unlesss you have a serious problem(which you dont cuz the cardiologist said your ok) you heart isnt skipping a beat

Yes, it is completely normal with anxiety. If you feel it is happening more than normal tell your Dr. during your next visit. Make sure you are not consuming too much caffeine or other stimulants.
