- One Heart Beat
- Sinoatrial node creates an electrical impulse
- The electrical impulse travels across the walls of the right atria
- Atrial systole is triggered
- The atrioventricular node recognises the impulse
- It causes a short delay to allow the atria to completely empty
- It then carries the impulse through the purkyne fibres in the septum of the heart
- The impulse enters the ventricles
- Ventricular Systole is triggered
