The Propensity for Inducing Atrial Fibrillation: A Comparative Study on Old versus Young Rabbits
Figure 2
Representative histological sections of atria and ventricles from old and young rabbits. (a) Atrial cross section from a young rabbit (3-4 months). (b) Atrial cross section from an old rabbit (4–6 years). Neither atrial section showed appreciable interstitial fibrosis. (c) Ventricular cross section from a young rabbit. (d) Ventricular cross section from an old rabbit. Note the marked interstitial fibrosis and scar compared to (c).
