Not a problem at all needing to go off line @Lee71 . You did the right thing.
I had to wear a heart monitor for 24 hours too, a few years ago. Same result as you. Anxiety.
My normal blood pressure is on the low side, typically 100/60 and heart rate around 70 bpm. But all that changes very rapidly, once anxiety is added to the mix.
Anyway ... it sounds like you're okay now, which is great.
Are you feeling mentally and physically exhausted after your long therapy session today?
Can I ask if you are doing any particular type of therapy?
