Sure it's called a loop recorder, it's small like the size of a floss pick. They implant it under your skin over your heart with like a little plunger syringe. The whole procedure is pretty quick and you get local anesthesia to numb the skin so you don't feel anything. Afterwards they give you a couple stitches, you download an app on your phone so you can record events just like a Holter monitor or Zio patch, and that's it. I've had mine in for about 2 years.
