Clinical Significance of Bundle of His & Purkinje fibre
The Clinical Significance of Bundle of His & Purkinje fibre are as follows
- Conduction Pathway: The Bundle of His transmits impulses from AV node to ventricles, ensuring coordinated heart contractions.
- Ventricular Contraction: Purkinje fibres coordinate sequential ventricular muscle activation, vital for effective blood pumping.
- Arrhythmia Connection: Bundle/Purkinje issues can cause arrhythmias, highlighting their role in diagnosing and treating heart rhythm disorders.
- ECG Insight: Changes in ECG patterns related to these structures aid diagnosis of conduction abnormalities.
- QRS Complex: Signifies ventricular depolarization, initiated by the Bundle of His and transmitted through Purkinje fibres, resulting in ventricular contraction.
- Therapeutic Impact: Implantable devices target Bundle/Purkinje for interventions like pacemakers, optimising cardiac function in conduction disorders.
Difference Between Bundle of His and Purkinje Fibers
The Difference between Bundle of His and Purkinje Fibres lies in function, structure, and location in the body. The bundle of His and Purkinje fibres are both components of the cardiac conduction system, playing critical roles in the transmission of electrical signals through the heart. Electrical impulses are sent from the AV node to the Purkinje fibres via the bundle of His, which serves as a bridge connecting the atria and ventricles. In this article, we will learn about his and Purkinje fibres’ bundles, function, location, and differences.
