While studying how the heart is formed, scientists serendipitously found a novel cellular source of atrial fibrillation (AF), the most common type of abnormal heart beat. They identified a population of cells in the atria of the heart and pulmonary veins of humans and mice that appear to be the seat of AF. The finding may lead to a more precise way to treat AF, with reduced side effects.
