Single Choice

Which of the following is the correct pathway for propagation of cardiac impulse?

ASA node $$\rightarrow$$ AV node $$\rightarrow$$ Bundle of His $$\rightarrow$$ Purkinje fibres
Correct Answer
BAV node $$\rightarrow$$ Bundle of His $$\rightarrow$$ SA node $$\rightarrow$$ Purkinje fibres
CSA node $$\rightarrow$$ Purkinje fibres $$\rightarrow$$ AV node $$\rightarrow$$ Bundle of His
DPurkinje fibres $$\rightarrow$$ AV node $$\rightarrow$$ SA node $$\rightarrow$$ Bundle of His.

Solution

Cardiac impulse generates from SA node then it reaches to AV node, then to bundle of HIS and finally to Purkinje fibers, this is how the cardiac impulse is generated.
So, the correct option is 'SA node
→→ AV node →→ Bundle of His →→ Purkinje fibers'.
