Quantifying atrial fibrillation to improve risk estimation: the growing role of AF burden and a new density kid on the block

The steps towards a quantitative AF diagnosis. The first column shows five exemplary patients with AF and their AF episodes. The next column shows the current, binary diagnosis of AF based on a few ECGs. The next column illustrates how AF burden would enable a quantitative diagnosis of AF. The final column illustrates how AF density could further refine AF diagnosis.
