His bundle

The His bundle is a special group of nerve fibers in the heart that help coordinate its rhythm. It acts as a pathway, transmitting electrical signals from the heart's upper chambers (atria) to the lower chambers (ventricles). This ensures the heart beats in a synchronized and efficient manner. Proper functioning of the His bundle is essential for maintaining a normal heart rhythm. If the His bundle doesn't work correctly, it can cause abnormal heart rhythms or delays, which may require medical evaluation or treatment like pacemakers.
