Photomicrographs of right auricular specimens of atrial tissue. Hematoxylin and eosin stain; magnification, ×110 in A,C,E (general view); ×440 in B,D,F (detailed view). (A, B) Normal atrium. (C, D) Atrium with fibrosis. (E, F) Atrium with myolytic perinuclear vacuoles.

3. Fig 2
Electron micrographs of atria with myolysis. The vacuoles are not membrane bound, filled with granular material, and contain lipofuscin particles, or are adjacent to the lipofuscin particles (A–C). Occasionally, two adjacent cells show a different density of contraction bands (C). Mitochondria are usually intact (D).
