What is the bundle of His composed of?
The bundle of His comprises of a complex organization of cells, predominantly consisting of Purkinje-type cells, slender transitional cells, broad transitional cells, and varying amounts of pacemaker cells.
What is a His bundle?
The bundle of His is a group of fibers that carry electrical impulses through the center of the heart. If these signals are blocked, you will have problems with your heartbeat. Watch this video about:Cardiac conduction system. The His bundle electrography is part of an electrophysiology (EP) study.
What is the bundle of His function?
The bundle of His is a part of the electrical system of the heart. It is a collection of cells that carry electrical signals from the AV node to the bundle branches. The electrical system that controls the heartbeat is made up of several parts that signal the heart muscle to contract.
What septum is the bundle of His located in?
The bundle of His is an important part of the electrical conduction system of the heart, as it transmits impulses from the atrioventricular node, located at the anterior-inferior end of the interatrial septum, to the ventricles of the heart.
Where is Bachmann’s bundle?
left atrium
In the heart’s conduction system, Bachmann’s bundle (also called the Bachmann bundle or the interatrial tract) is a branch of the anterior internodal tract that resides on the inner wall of the left atrium.
What is a His bundle lead?
His-bundle pacing is a feasible method for delivering permanent pacing. It produces physiological ventricular activation via the His-Purkinje system. His pacing offers an alternative bradycardia pacing modality to right ventricular pacing and has the advantage that it does not cause intraventricular dyssynchrony.
What does the Bachmann’s bundle?
Bachmann’s bundle (BB), also known as the interatrial bundle, is well recognized as a muscular bundle comprising of parallel aligned myocardial strands connecting the right and left atrial walls and is considered to be the main pathway of interatrial conduction.
Where is the interatrial bundle?
Where are the bundles of his branches located?
The bundle of His branches into the left and the right bundle branches, which run along the interventricular septum. The left bundle branch further divides into the left anterior and the left posterior fascicles. These bundles and fascicles give rise to thin filaments known as Purkinje fibers.
What kind of fibers are in the bundle of his?
The AV node tapers down into the bundle of His, which passes into the ventricular septum and divides into two bundle branches, the left and right bundles. Sometimes the ‘left and right bundles of His’ are called Purkyně or Purkinje fibers .
Where is the bundle of his located in the heart?
The bundle of His is an elongated segment connecting the AV Node and the left and right bundle branches of the septal crest. It is approximately 1.8 cm long in an adult heart [4] and is primarily located deep within the dense connective tissue.
Who was the discoverer of the bundle of his?
Discovered in 1893 by Swiss-born cardiologist and anatomist Wilhelm His Jr., the bundle of His or His bundle is a collection of heart muscle cells specialized for electrical conduction.
