Perinexus in Health and in Disease

Caption

The transmission electron microscopic image on the left is a collapsed perinexus in the heart of a person without atrial fibrillation. The image on the right is an expanded perinexus in the heart of a person with atrial fibrillation. The more the perinexus separates heart cells, the more difficult it can be for the cells to communicate. The perinexus is tenths of a millimeter wide.
