Svt in pregnancy

[blessedmammy]

I’m nearly 12 weeks pregnant and have svt. My episodes up to now are quite infrequent but when they happen my hr gets to 220, treated with adenosine. I am petrified of this happening during my pregnancy especially in my first and second trimester when the baby isn’t classed as viable. I’m not seeing my cardiologist until Thursday and I’ve got myself into such a state thinking of what could happen to my baby if it happens! I’m so scared it happens in the first trimester and the stress it puts on my body causes me to loose the baby 😞 I wish I could control my anxieties but I just cannot, when I have an attack I feel like I’m dying. If anybody has had episodes in early pregnancy please tell me everything was ok with your pregnancy because I feel like we have no hope💔

Hi @blessedmammy ! I started to have SVT during my first pregnancy. Episodes only started in my third trimester. I went to a&e with a HR or 220 as well! They thought me how to do a vagal manoeuvre (blowing a syringe as much as I can then lifting my legs!). I had 2 more episodes in 3rd trimester.
I had been referred to the cardiology department and they advised to ask for an epidural during labour.
Once I had my baby (who was perfectly fine btw 😊), they attempted an ablation but could not trigger it so left it as it is.
Now in my second pregnancy (currently 23 weeks) and already had 3 episodes. As soon as I feel it starting, I do that manoeuvre and it goes down in a few minutes. I asked the GP to be referred again to cardiology department. I had a call with the maternity clinic last week and they told me I could come for monitoring baby if it happens again especially after 26 weeks.
Hope this helps a bit!
Mention this to the midwife and inform your cardiologist that you are pregnant, hopefully they will arrange for you to be followed by a team at the hospital

Thank you so much for the reply @Loute02 ❤️

I also had a failed ablation a long time ago and have never reattempted one. Do you get many episodes outside of pregnancy? Luckily for now I don't, but my palpitations during pregnancy have been wild! I see my cardiologist on Thursday so hopefully they can make me feel more at ease. I just wish more than anything this wasn't something I had to worry about on top of everything else! I've had a natural delivery and a c section and been fine with both, both times I had the epidural so think that's the way I'll go with this labour also!

I only had one other episode this year when I wasn't pregnant which made me a bit worried as I thought it would just be pregnancy related!
It always comes at random times for me, not even when I'm stressed.
If you are worried about it when it happens, I would suggest ringing the hospital and ask for an extra scan. Hopefully you won't have any and can focus on other things!

@blessedmammy I get episodes of SVT, ranging in length and heart rate speed, although I haven't had an episode as fast at 220 in a few years and have never needed drugs to help stop it as the maneuvers have always worked eventually. My cardiologists have always been very blaze about it and said its nothing to worry about, even during pregnancy... I had one longish episode of about 30 minutes during my first trimester with my current pregnancy (now 31 weeks) and after 3 miscarriages and nothing bad happened to the baby or myself in anyway, just to hopefully reassure you. I'm now getting loads of skipped heart beats rather than the svt, but again the cardiologist isn't worried as there's nothing structurally wrong with my heart. They are extremely uncomfortable/unnerving though!
