The fine structural alteration and histochemical changes of the cardiac conduction system were studied in dogs and rats using various models of ischemic and reperfusion injury. The role of Ca2+ overload and reactive oxygen species (ROS) per se were also investigated. In all models of injury the activity of glycogen phosphorylase (histochemical indicator of the early ischemic changes) was present in nodal and conducting cells, although it was markedly diminished or absent in surrounding contractile muscle. Fine structural ischemic alterations progressed more slowly in conducting cells in comparison with working myocardial cells. Changes induced by Ca2+ paradox or ROS were reversible in conducting tissue in contrast to working myocardial tissue. The observations support the concept that conducting cells are more resistant to ischemia and also to reperfusion related injury than contractile myocardial cells.
