A nurse is reviewing the electrocardiogram (ECG) results. Which portion of the conduction system does the nurse consider when evaluating the P wave?

A.

SA node

B.

AV node

C.

Bundle of His

D.

Purkinje fibers

Answer and Explanation

The Correct Answer is A

A. The P wave represents atrial depolarization, which is initiated by the SA node, the heart's natural pacemaker.  

 

B. The AV node is responsible for conducting impulses from the atria to the ventricles but does not initiate the P wave.  

 

C. The Bundle of His transmits the electrical impulses to the ventricles but is not directly associated with the P wave.  

 

D. Purkinje fibers are involved in ventricular depolarization, which corresponds to the QRS complex, not the P wave.
