HOW DOES THE CONDUCTION SYSTEM OF THE HEART CONTROLS THE CARDIAC CYCLE	1. (atrial diastole) Atria fill with blood during atrial diastole or relaxation phase / repolarisation occurs 2. (ventricular diastole) (pressure builds in the atria) blood travels (passively) into the ventricles during ventricular diastole or relaxation phase of ventricles 3. (SA Node) CS1 Sinoatrial node or S A node or SAN initiates or sends an impulse 4. (atrial systole) ....impulse spreads across atria causing atrial systole or contraction of both atria / atrial depolarisation 5. (remaining blood) This causes the remaining blood in the atria to be pushed (actively) into the ventricles 6. (AV node) impulse reaches AV or atrio ventricular node or AVN 7. (B of H impulse distributed or continues down the bundle of His 8. (ventricular systole) this causes ventricular systole or depolarisation or contraction of both ventricles (from the bottom upwards)
