I experience SVT episodes approximately one a month. I also like travelling a lot. I know vagal maneuvers, I carry beta-blockers, but all these stuff don't always stop SVT episode, so I need to call an ambulance sometimes. What to do if SVT occurs in the wild - mountains, remote countryside, forest? I heard that it is not allowed to walk or hike with SVT, so I won't be able to reach a place to where the ambulance can come if an episode occurs.
