Where can right and left bundle branch blocks be differentiated?
A)In the precordial leads
B)In the limb leads
C)In the bipolar leads
D)In the augmented leads

Question

Quizplus · Accepted Answer

Right and left bundle branch blocks can be differentiated in the precordial leads because they provide a better view of the electrical activity in the ventricles. In right bundle branch block, there is a delay in the impulse traveling through the right bundle branch, resulting in a wide QRS complex in leads V1 and V2. In left bundle branch block, there is a delay in the impulse traveling through the left bundle branch, resulting in a wide QRS complex in leads V5 and V6.
