Which term describes the conduction pathway that connects the AV node to the bundle branches?

• A. Bundle of His
• B. Cardiac cycle
• C. Electrodes
• D. Precordial leads

Answer: (A)

The Bundle of His is the conduction pathway that connects the AV node to the bundle branches. It sits in the upper part of the interventricular septum and carries the electrical impulse from the AV node onward, where it splits into the right and left bundle branches and then into Purkinje fibers to rapidly stimulate the ventricles. This rapid transmission ensures the ventricles contract in a coordinated way after the atria have emptied. The other terms aren’t conduction pathways: the cardiac cycle describes the sequence of heartbeats, electrodes are sensors that detect electrical activity, and precordial leads are ECG chest placements.
