Hello @retiredminnesotans, Welcome to Connect. Thanks for starting this discussion. Many years ago I had a Sleep Number bed before they had all the bells and whistles that they now have. Ours was only adjustable but didn't have any other features. The new smart bed does sound pretty amazing. I did find a small research study on the technology that was pretty interesting.

It's great that you were able to use the data to detect your wife's A-fib and get treatment quickly and then monitor it to detect a future A-fib episode. Did your wife's A-fib treatment change after the second episode?
