Following are the stages of pathway for conduction of an action potential through the heart A. AV bundle B. Purkinje fibres C. AV node D. Bundle branches E. SA node Choose the correct sequence of pathway from the options given below
  1. A-E-C-B-D
  2. B-D-E-C-A
  3. E-A-D-B-C
  4. E-C-A-D-B

Solution

Correct answer is option (4) because the correct pathway of conduction of action potential is $\mathrm{SA} \rightarrow \mathrm{AV}$ node $\rightarrow$ AV bundle $\rightarrow$ Bundle branches $\rightarrow$ Purkinje fibres
