The velocity of conduction in the Purkinjie fibers of the heart is__________________?
Correct answer: D. 1 to 4 m/sec
- A. More than 12 m/sec
- B. 5 to 8 m/sec
- C. 9 to 12 m/sec
- D. 1 to 4 m/sec
Explanation
Purkinje fibres conduct impulses at about 1.5–4 m/s, the fastest conduction rate in the cardiac conduction system. This rapid spread allows near-simultaneous ventricular contraction.
