Yes. It started when i was pregnant and turns out that i have a heart defect that causes palpitations and tachycardia. Obviously, that's not the normal outcome, though.

Good luck! Its definitely scary when you think there might be something wrong with your heart.

I had problems with SVTs during my first pregnancy. A few times the palpitations would make me pass out. It turned out I had a heart condition (known as AVNRT) and had a cardiac ablation done when LO was a few weeks old. Now I'm on my second pregnancy and haven't had any issues. My situation definitely wasn't the norm though - I know many people have palpitations during pregnancy with no underlying conditions. Good luck at the cardio. He may have you wear a monitor for a few days. That's how they eventually picked up my issues.

I did and when I mentioned it to my MD she suggested I make sure I am keeping myself hydrated. I paid really close attention to my water intake and there was for sure a correlation and they didn't happen as long as I drank enough water. Hoping this is the case for you!!

i have them a lot but never remember to ask about them when i'm at the dr! i feel like i get them after i eat a lot... i have an OB appt next week so i'll be sure to ask, thanks for reminding me!

I have had them a handful of times, my OB did not seem too concerned.

I had them with my first pregnancy but my OB wasn't concerned. Nothing with the second pregnancy.

I have a heart condition with palpitations that was diagnosed much before my pregnancy, it was worse when i had caffeine so i cut that out of my diet years ago and mostly eliminated the palpitations. Now that i'm pregnant i get them occasionally.

When i first got the palpitations I talked with my sister about it who is in med school (for neuroscience, so it's unrelated to cardiac but she's very very smart) and she did some research for me. She found some medical studies that showed you could get rid of the palpitations by plugging your nose and blowing like you're trying to pop your ears. Sure enough, it works for me every time! Doesn't cure anything, but gets rid of the discomfort

@turkeylurkey: i just checked in on this thread cuz i'm currently feeling like my heart is RACING and was wondering if you got any results. good to hear everything seems healthy.... i'm feeling a bit worried but wondering if it's just stress as well.

My sister is in the hospital now for SVT. Her HR was upto 189 (laying on the couch) when I saw her at her home yesterday. I was trying to convince her to go to UC or something. She ended up going to the ER last night. They gave her some meds to restart her heart pattern. It seemed to have worked so far and she is hoping to be discharged today. She is 23 weeks pregnant with twins. I hope the meds work because I think if it doesn't work, the next step would be to sedate her and give her an electric shock. Hoping she doesn't need that. Oh, good news is the babies are doing well and is not really affected. The were more worried about my sister.

I developed this prior to pregnancy, went through a ton of testing, and they determined it happens "unknown causes"....however, they did say that a number of things can trigger them to happen: not enough water, too much caffeine (including chocolate), not enough sleep, too much stress, etc. I have yearly check ups and testing to monitor it. I had the all clear before we tried getting pregnant. He said that pregnancy can trigger them more or make them go away. I luckily have not had more of them, just one minor one. However, once I became pregnant, my ob/midwife ran additional thyroid testing and it came back too high for pregnancy (they were within normal range although on the higher side pre-pregnancy) so I've been on medicine for my thyroid since then. Your thyroid levels apparently can trigger them.

I had tachycardia with my second pregnancy pretty early on like around 6 weeks. It ended in m/c at 8 so I was never really treated for it. Very strange too since it never happened during my other pregnancies.

@bluestriped bee: That's exactly what I had. The cardio said the extra circuit had been there forever, but was triggered by pregnancy. I had an ablation done post-pregnancy and haven't had any issues since. Good luck to her!
