I'm 21 years old and have been experiencing a feeling of my heart skipping a beat or speeding up almost daily since I was pregnant. My son is now 5 months old and they've continued. I've worn a holter monitor three times over the past year. Today I got a call from my last one. The woman told me I have "significant pauses in my heart beat, of up to 4.8 seconds long". Is this a huge cause for concern? She wasn't sure and said the dr will call when he can to discuss, but couldn't get me an appointment until next week. Can this wait a week? I'm not experiencing any pain or anything with the palpitations, other than occasionally feeling like I need to breathe deeper to catch my breath. Like I said, I'm only 21, no underlying causes I know of nor any other medical problems, normal blood pressure, not overweight or anything. I'm breastfeeding and trying to keep my fluid intake up but I've always been bad with that. What could be causing these heart flutter feelings?
