interventrikulærgren

Interventrikulærgren is a term used in cardiac anatomy and electrophysiology, referring to a specific part of the electrical conduction system of the heart. More precisely, it describes the branching fibers that carry the electrical impulse from the bundle of His to the ventricular myocardium. After the bundle of His, which originates from the atrioventricular node, the impulse travels down the interventricular septum. Within the septum, the bundle divides into the left and right bundle branches. The interventrikulærgren then encompasses the further subdivisions of these branches as they spread out into the walls of the left and right ventricles.

These fibers are crucial for coordinating the contraction of the ventricles. The electrical signal travels rapidly through the interventrikulærgren, ensuring that both ventricles contract almost simultaneously. This coordinated contraction is essential for efficient pumping of blood to the lungs and the rest of the body. Any disruption or damage to the interventrikulærgren can lead to abnormalities in the heart's rhythm and pumping function, often manifesting as conduction blocks or arrhythmias. Conditions affecting the interventricular septum, such as congenital heart defects or myocardial infarction, can compromise the integrity of the interventrikulærgren. Diagnostic tools like electrocardiograms (ECGs) are used to assess the electrical activity of the heart and can reveal abnormalities related to the interventrikulærgren.
