I used to have palpitations and ignored them, and then one night they turned into SVT and I ended up in Resus in A&E. My heart was was 195bpm and stayed that way for just over an hour until they got it under control.
I was given a drug to very temporarily stop my heart (and I mean for about a second, probably less) in the hope that when it re-started the heart rhythm would be normal again, but it wasn’t and so I had to have a second, double dose, of the medication again. Thankfully the second dose worked otherwise they would have had to sedate me and shock me with the paddles they use when people have a cardiac arrest.
My heart rate went down to 101 and they let me go home.
A week later it happened again but thankfully it self-resolved without me needing that medication again.
I was started on beta-blockers and referred to see a cardiologist.
I had standard ECGs, a 24 hour ECG and a heart ultrasound. None of them raised any concerns.
I also was referred for a cardiac ablation procedure which was not pleasant (they got my heart beating at over 210bpm) to try and induce palpitations but not such luck. They did find out I had a really bizarre cardiac pathway and I had some nodes there that shouldn’t be that were affecting my heart rate but there was nothing that could be done about it.
So to cut a long story short, I was discharged from cardiology with no treatment required but I did remain on the beta blockers.
You are absolutely doing the right thing getting checked out early. I often wonder if I’d acted on it much quicker than all the SVT episodes could have been avoided.
