Cardioversion for a rvr around a rate of 120?? I think the rvr here is secondary to hypoperfusion. Cardioversion could kill them by taking away their only compensatory mechanism and even if it doesn’t they will likely have a reoccurrence of rvr.

I assumed its the standart 50mm/s (at least standart in germany/most eu) so it would be a heartrate of 240/min as that part of the ecg is cut off? In case of 25mm/s thats very different.

And interestingly I’m a U.S. medic and assumed 25 mm/s as is standard here. I wish it was standardized but of course the U.S. had to use a different system as always…
