Well, in my case, my chads score was also 1, and my Electrophysiologist also, did not want to put me on a blood thinner, with only a couple documented A-Fib attacks. Then something happened, that changed the picture. My neurologist was alarmed at some sudden neurological symptoms that I had, so she ordered an MRI. The MRI revealed that I had suffered a couple strokes recently. The next day, my electrophysiologist put me on Eliquist blood thinner! Furthermore, a Watchman implantation is planned for March! Make of it what you will, but that’s my story!
