I had an incident and VNS helped
Last week I did something that over stimulated myself and my heart rate got stuck at 150BPM, @55 yrs old, not a good thing, but I do HIIT and it does get up to there. It may have been terminal if my HRT stayed up there, I called an ambulance and as soon as they put a drip in my arm my HRT went down, I went to the hospital and got checked out, but my HRT was still abit high and one of the DRs was saying that stimulating my vagus nerve is the thing to bring it down if it ever happened again. After I got home my HRT still seemed to be racing and it was still abit elevated, so over the next 3 evenings before bed I did 5 minutes each side on my vagus nerve using my US2000 ultrasonic device and my HRT is back to normal, so I'm glad that I have proven the stimulation has worked. Hopefully my HRT will be back in its normal rhythm now, but at least I know what to do in the future if it happens again.
