@paula3166 Interesting, i assumed when you said arrhythmia it was a fast one with me it would go up to near 200 and effectively stop moving blood.
With yours it is slow so your stopping is more because of a low heart rate im guessing? I just never heard it called an arrhythmia before. So im not sure how much I can help further except I have had both internal and external ablations and can maybe help with the process of an ablation. When ever I had an episode tho it was more urgent. Like it need to be solved in under a minute or so which is why I had a difbulator also.
Well I'll be available for questions and look forward to hearing more once you find out. The Heart is an amazing organ but also Mayo is on the cutting edge of research in many areas. I'm pretty confident they will figure this out.

Just as an example unrelated to the Heart, I developed a fever mid 2019 and was hospitalized due to low blood counts. I realized first hand how Mayo Doctors don't give up. They literally tested every part of my body to find the source of this fever, normal blood test could not find it and I was simultaneously dealing with some other viruses, so I was there 5 weeks and finally they found a virus in my lungs that doesn't get into the bloodstream. The only way they found it was to put a scope into my lungs with a rinse then removed the solution and that's when they found it. A simple antibiotic took care of it. But my point is they are determined to help and won't stop until they do what they can. It helps a lot that they have staff doctors of almost every specialty so it makes diagnoses much quicker than other hospitals I've been too.

I look forward to hearing more.
