From the sinoatrial node in the right atrial wall, the impulse spreads across the atria to the AV node, down the bundle of His, and out across the Purkinje fibres that fire each ventricular contraction. The pendant traces that path. The Science Behind the Conduction System The cardiac conduction system begins at the sinoatrial (SA) node in the
