A MODIFIED METHOD FOR EXAMINING THE CARDIAC CONDUCTION SYSTEM

A revised technique is described in which the sino-atrial node, the at rio-ventricular node and the distal part of the His bundle and the bun dle brances of the cardiac conduction system are demonstrated in longi tudinal sections through cutting of 4-5 blocks. The longitudinal secti oning allows observation of continuity between different components of the cardiac conduction tissue. This method reduces the workload and h opefully encourages the pathologist to make the examination of the car diac conduction system a part of the routine procedure.
