Purkinjekiududest

Purkinjekiududest refers to the Purkinje fibers, which are specialized cells within the heart's electrical conduction system. These fibers are responsible for transmitting electrical impulses from the atrioventricular (AV) node to the ventricles, triggering their contraction. They form a network that rapidly disseminates the signal throughout the ventricular muscle, ensuring a coordinated and efficient pump.

Originating from the bundle of His, the Purkinje fibers are characterized by their large size and abundant glycogen content, which facilitates rapid conduction of electrical signals. This rapid conduction is crucial for the synchronized contraction of the ventricles, which is essential for effective blood ejection. Disruptions in the function of Purkinje fibers can lead to various cardiac arrhythmias, such as ventricular tachycardia or fibrillation, where the heart's rhythm becomes irregular and potentially life-threatening. Understanding the role and properties of Purkinje fibers is fundamental in cardiology for diagnosing and managing a range of heart conditions. Their unique structure and function make them a vital component of maintaining a normal heart rhythm.
