Conduction velocity is least in_______________?
Correct answer: A. AV node
- A. AV node
- B. SA node
- C. SA node
- D. Purkinje fibers
Explanation
The AV node has the slowest conduction velocity, creating a delay that allows the ventricles to fill before ventricular contraction. Purkinje fibres conduct most rapidly, while the duplicated SA-node options are not the best answer.
