They are set with thresholds, typically 185 bpm. Additionally, they have a correlation setting. It monitors your rhythm at 100 bpm and then if you get to 180 and the rhythm is off, you got a fun shock. I don't know about OP< but I can safely work outwith mine, just slowly.

Correct, the manufacturer and I are currently discussing the going rate for that programming error

This might get downvoted, but I've had about 5 open heart surgeries; I'm so glad yours came out ok! Just to let you know, the next 2 months will be rough. Coming out of surgery like this there is a feeling of extreme happiness/ gratefulness for the first week to 2 weeks, then it gets rough.
You'll get frustrated that the healing takes so long, that you can't do simple things... it gets hard. If you need someone to talk to when that happens, feel free to PM me and I'll give you my phone number. Again, congrats on it going so well, and enjoy your rest while you can get it!

I've had heart surgery 5 times and my ICD has blasted me 8 times; if you ever need to talk let me know; I volunteer as a counselor at the heart camp for my local children's hospital.
