A report on Electrical conduction system of the heart
The electrical conduction system of the heart transmits signals generated usually by the sinoatrial node in the heart to cause contraction of the heart muscle.

Heart
10 linksMuscular organ in most animals.
Muscular organ in most animals.
These generate a current that causes the heart to contract, traveling through the atrioventricular node and along the conduction system of the heart.
Sinoatrial node
6 linksGroup of cells known as pacemaker cells, located in the wall of the right atrium of the heart.
Group of cells known as pacemaker cells, located in the wall of the right atrium of the heart.
These cells can produce an electrical impulse (action potential) that travels through the electrical conduction system of the heart, causing it to contract.
Arrhythmia
5 linksToo fast or too slow.
Too fast or too slow.
Arrhythmias are due to problems with the electrical conduction system of the heart.
Cardiac pacemaker
5 linksInitiated by electrical impulses known as action potentials.
Initiated by electrical impulses known as action potentials.
Sometimes an ectopic pacemaker sets the pace, if the SA node is damaged or if the electrical conduction system of the heart has problems.
Purkinje fibers
4 linksThe Purkinje fibers (often incorrectly ; Purkinje tissue or subendocardial branches) are located in the inner ventricular walls of the heart, just beneath the endocardium in a space called the subendocardium.
The Purkinje fibers (often incorrectly ; Purkinje tissue or subendocardial branches) are located in the inner ventricular walls of the heart, just beneath the endocardium in a space called the subendocardium.
Purkinje fibers allow the heart's conduction system to create synchronized contractions of its ventricles, and are essential for maintaining a consistent heart rhythm.
Cardiac muscle
5 linksOne of three types of vertebrate muscle tissue, with the other two being skeletal muscle and smooth muscle.
One of three types of vertebrate muscle tissue, with the other two being skeletal muscle and smooth muscle.
Other potential roles for fibroblasts include electrical insulation of the cardiac conduction system, and the ability to transform into other cell types including cardiomyocytes and adipocytes.
Atrioventricular node
3 linksThe atrioventricular node or AV node electrically connects the heart's atria and ventricles to coordinate beating in the top of the heart; it is part of the electrical conduction system of the heart.
Bundle of His
2 linksCollection of heart muscle cells specialized for electrical conduction.
Collection of heart muscle cells specialized for electrical conduction.
As part of the electrical conduction system of the heart, it transmits the electrical impulses from the atrioventricular node (located between the atria and the ventricles) to the point of the apex of the fascicular branches via the bundle branches.
Electrocardiography
4 linksProcess of producing an electrocardiogram , a recording of the heart's electrical activity.
Process of producing an electrocardiogram , a recording of the heart's electrical activity.
Interpretation of the ECG is fundamentally about understanding the electrical conduction system of the heart.
Bundle branches
2 linksThe bundle branches, or Tawara branches, are offshoots of the bundle of His in the heart's ventricle.
The bundle branches, or Tawara branches, are offshoots of the bundle of His in the heart's ventricle.
They play an integral role in the electrical conduction system of the heart by transmitting cardiac action potentials from the bundle of His to the Purkinje fibers.
