This is a recording from a middle aged woman with recurrent atrial fibrillation. She was treated with flecainide with some improvement of her symptoms. The above is a recording taken in the cardiac clinic. It shows group beating with sinus rhythm. There are missing P waves. This suggests that there is sinus node arrest or that this is sinus node exit block.
