A friend of mine in his early twenties drowned a few months back due to a cardiac event related to atrial fibrillation. He was otherwise in phenomenal shape and living life to the fullest.
I’m really sorry that happened to your friend and to you. I think the best outcome of tech like this is that it makes what seems like maybe small and maybe seemingly mundane improvements that reduce the frequency that things like this happen.
I'm sorry about your friend. I hope this isn't insensitive, but could you elaborate any more on what happened? I'm an a-fib sufferer with a pool so I'm quite curious.
