Photographs of cadaveric heart specimen showing four regions from where the samples were obtained: sinoatrial node (SAN), the atrioventricular node (AVN), working myocardium of the right atrium (RAM) and working myocardium of the right ventricle (RVM). Histological images (Masson’s trichrome staining) showing sections through the SAN and AVN (compact node, penetrating bundle and His bundle).
