So for context, I randomly started having SVT episodes back in March that landed me in the ER 4x in 6 weeks. Had to receive adenosine each time to correct. Because of how frequent the episodes were, and the fact I could never self-avert, I was able to get an ablation quickly. I’m also on propranolol for anxiety/a super reactive HR.

Fast forward 8 weeks post-ablation, and I’m having some weird/scary overnight occurrences. First, I’m definitely having the vivid nightmares warmed about on propranolol. But now I’m also having instances of waking up feeling “off” (that pre-SVT feeling) with my heart starting to pick up pace or pound, which then sends me into a panic attack. We’ve basically chocked it up to ✨anxiety✨

Well, as I write this, I just had another episode but noticed there might be a legit physical component/trend. I realized that most times when this happens, it occurs shortly after I wake up randomly drenched in sweat. Like, crazy sweat.

I’m thinking that I’m having random adrenaline dumps overnight, which ofc feel similar to pre-SVT episodes and freak me TF out. The question is…what is causing those? Could it be the propranolol? Is there a different heart or health issue going on?

30F, history of panic attacks (started when I was 25), and had preeclampsia/my first baby last February. I started having my first episodes of SVT in March, which sent me by ambulance to the ER 4x in 6 weeks. They had to give me adenosine to get me out of it, I could never self-avert. Most times, I actually ended up feeling paralyzed bc I guess my muscles weren’t getting enough oxygen and the build-up of carbon dioxide made my whole body cramp up. Literally felt like I was dying, so major PTSD lol.

Finally got an ablation in May. They were able to induce the arrhythmia pretty immediately, even under anesthesia. EP also found I had a naturally high resting HR that was super reactive to any increase in adrenaline. Ablation was deemed a success, and I’m now on 80mg propranolol to manage the reactive heart symptoms.

I’m a little over a month out, and while I’ve definitely not had any SVT, I’m still getting occasional feelings that remind me of it…feeling “off”, slight winded feeling, even a little nauseous/sweaty. Which, ofc, usually triggers an anxiety attack lol. I’ve been able to get back to normal with cold packs, a shower, or targeted distraction methods. But it still makes me nervous—Do I have a new or different cardiac issue? Why did it start in the first place, and could it come back?

Just seeking some validation, reassurance, or shared experience with SVT, anxiety, and post-ablation!!
