I don’t know if my comment will help but because of your symptoms description, I may have a clue for you. I was born with a birth defect in my heart, a 1 in a million defect. After much research, it wasn’t until 2021 that I discovered I had WPW, Wolff, Parkinson, White Syndrome. I had lived 77 years with all the heart problems I have, not realizing it was WPW causing everything, including 3 heart attacks. Does this description sound familiar? I call them Spontaneous Blackouts! One second you’re standing, the next second you’re on the floor/ground wondering what you might have injured from the fall. There’s no warning at all with very little knowledge of what just happened. There’s no dizziness, lightheadedness, like fainting causes, just complete and instant unconsciousness. With that knowledge in hand and a pcp willing to help me prove my case of WPW, I realized I was seeing the wrong heart specialist. I needed to be seen by an Electrophysiologist Cardiologist, a specialist in Heart Rhythm issues. My heart is now being monitored 24/7 by an expensive loop heart recorder emplaned in my chest to track down the bad heart cells causing my problems, so they can be destroyed. You’ve had a ablation but that may not have solved your problem because my heart defect is actually a short circuit loop of cells between the SA Node and the AV Node which an Electo Cardiologist could find. Since you didn’t mention what type of doctor did it, I just wanted to tell you of my experience with Blackouts. Good luck.
