The downward slope - Conduction of the heart - Ventricular conduction
6 important questions on The downward slope - Conduction of the heart - Ventricular conduction
What structures are involved in ventricular conduction?
- fibres which carry the impulse from the AVN to the bottom of the ventricle.
- carried to the bottom of the ventricle to ensure that the ventricle contracts from the bottom upwards- prevents the pressure of the ventricles rising and bursting.
- split into the right and left bundle branches
- further splits into smaller fibres called the perkunje fibres
Why is the transmission of the impulse down the bundle of his rapid?
What is the atrioventricular septum and what is its relevance?
- ensures that the signal only travels down the bundle of his.
- a continuous fibrous barrier which separates the atrial muscle from the ventricular muscle.
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
How far do the perkunji fibres penetrate the cardiac muscle?
Why does it take 0.06secs for the impulse to travel from the bundle to the most superficial ventricle muscle layer?
What is the importance of the perkunji fibres?
