The impulse is then passed to another node within the heart – the atrioventricular node (AVN) . This node is in the lower part of the right atrium.

WebSystole – Isovolumic contraction: As systole begins the pressure in the ventricle, which at this point is close to 0 mmHg) increases rapidly. When the ventricular pressure exceeds atrial pressure the atrioventricular valve closes. The closing of these valves is responsible for the first heart sound.
