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. What is a His bundle pacemaker?
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 is the bundle of His and Purkinje Fibres?
Bundle of His is a collection of specialized heart muscle cells that transmit electrical impulses from the AV node in the heart to the muscle cells of the heart wall. Meanwhile, Purkinje fibres are thin filaments that distribute electrical impulses to the ventricle myocardium and activate right and left ventricles. What does his stand for in the heart?

What is his in the heart?
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. Why is it called a Bundle of His?
It conducts the electrical impulses that regulate the heartbeat from the right atrium to the left and right ventricles. The bundle of His is named after its discoverer, German cardiologist Wilhelm His (1836–1934).
Frequently Asked Questions(FAQ)
What did Velu carry in his bundle?
Answer: Velu was carrying a bundle with him carrying a shirt, a towel, and a comb.
What is the His Purkinje system?
The His–Purkinje system is composed of specialized cells responsible for the synchronous activation of the ventricles. … In humans, a variety of monomorphic ventricular tachycardias can be sustained within the architecture of the Purkinje branches.
Which part is known as pacemaker?
The sinoatrial (SA) node or sinus node is the heart’s natural pacemaker. It’s a small mass of specialized cells in the top of the right atrium (upper chamber of the heart). It produces the electrical impulses that cause your heart to beat. … These are called demand pacemakers.
What is conducting system of heart?
Heart Conduction System (Cardiac Conduction) The heart conduction system is the network of nodes, cells and signals that controls your heartbeat. Each time your heart beats, electrical signals travel through your heart. … The expansion and contraction control blood flow through your heart and body.
What is the bundle of Kent?
What is the function of the His-Purkinje system?
The His-Purkinje System (HPS) is responsible for the rapid electric conduction in the ventricles. It relays electrical impulses from the atrioventricular node to the muscle cells and, thus, coordinates the contraction of ventricles in order to ensure proper cardiac pump function.
What are Purkinje Fibres in heart?
Purkinje fibers are specialized conductive myocardial cells with few myofibrils that promotes the rapid conduction of the impulse through the ventricles. They are larger than the normal myocardial fibers. The waves of depolarization ultimately spread to adjacent myocardial cells through the intercalated discs.
What is the function of Purkinje Fibres in the heart?
Purkinje fibers play a major role in electrical conduction and propagation of impulse to the ventricular muscle.

What is 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.
Can the bundle of His act as a pacemaker?
Further down the electrical conducting system of the heart is the Bundle of His. The left and right branches of this bundle, and the Purkinje fibers, will also produce a spontaneous action potential at a rate of 30-40 beats per minute, so if the SA and AV node both fail to function, these cells can become pacemakers.
Where is the bundle of His located?
In general, the His bundle is located adjacent to the annulus of the tricuspid valve, distal to the atrioventricular node, and slightly proximal to the right bundle branch and left bundle branch.

What is superior node?
The SA node is the heart’s natural pacemaker. The SA node consists of a cluster of cells that are situated in the upper part of the wall of the right atrium (the right upper chamber of the heart). The electrical impulses are generated there. The SA node is also called the sinus node.
What is Rbbb heart condition?
Right bundle branch block (RBBB) is an electrocardiogram finding that occurs when the physiologic electrical conduction system of the heart, specifically in the His-Purkinje system, is altered or interrupted resulting in a widened QRS and electrocardiographic vector changes.
What did Jaya eat Velu?
Explanation: They got two bananas and a vada. Velu ate one banana and a vada while Jaya took one banana.
Why did Jaya help Velu?
Answer: Jaya was a poor little girl ragpicker who carried a bag on her back. She collected waste material from the dustbins. … She helped Velu with food as well as a regular job as ragpicker.
What did Jaya and Velu get to eat?
A wedding was taking place there. She took him behind the hall near a big garbage bin that was overflowing with rubbish. (ii) Velu got a banana and a vada, while the girl got only one banana to eat.

Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
