A modified method for examining the cardiac conduction system.
A revised technique is described in which the sino-atrial node, the atrio-ventricular node and the distal part of the His bundle and the bundle brances of the cardiac conduction system are demonstrated in longitudinal sections through cutting of 4-5 blocks. The longitudinal sectioning allows observation of continuity between different components of the cardiac conduction tissue. This method reduces the workload and hopefully encourages the pathologist to make the examination of the cardiac conduction system a part of the routine procedure.
