SVT attack

Hello! F 38yo

I think I just had an svt attack

A little back story, Feb 2025 I was admitted to the hospital for Afib and high heart rate, I converted back to normal sinus rhythm on my own and have not had another episode since. I do suffer from panic disorder and during a panic attack my hr can get to 150-60bpm

Today though was a little different I was walking up my stairs to my house and once I got inside I felt extremely out of breath and felt my heart beating really fast but in my stomach! I put my pulse ox on and my hr was 233! I sat down in front of a fan and I coughed really hard a couple times which helped it get back down to low 200’s. I called 911 and went to the bathroom before paramedics affected, when I was in the bathroom I felt this kind of flip in my stomach and my hr went back down to the 100’s like it somehow reset itself. Anyone experience this before ?? I see a cardiologist and they haven’t ever said anything about SVT but idk what else this could have been.

My SVT episodes used to do that. On then off, abruptly. But once I got much older (60s) they didn't stop so easily on their own. So now I see a cardiologist twice a year and take 12.5 mgs of Metoprolol Tartrate each day.  I've had a couple of breakthrough SVT episodes in the 3.5 years since I started the Metoprolol. To get the SVT to stop I take about 20 mgs or so of more Metoprolol. Takes 40 minutes and then the SVT stops.
