Across
- 3. This is a specialised fibre that do not contract but passes electrical impulses to the base of the ventricles, with a short delay
- 4. This is the systole where both atrium contracts
- 7. node This is the pacemaker; it initiates contractions within the heart.
Down
- 1. This is a systole where excitation of electrical wave passes to the ventricles via the AVN
- 2. These are some sort of impulses that travel thorugh the atria to the ventricles
- 5. It can contract on it own.
- 6. This is where both ventricles and atria relax together
