Muscular organ in most animals that pumps blood through the blood vessels of the circulatory system.
These generate a current that causes the heart to contract, traveling through the atrioventricular node and along the conduction system of the heart.
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.
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.
Too fast or too slow.
Arrhythmias are due to problems with the electrical conduction system 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.
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.
Medical device that generates electrical impulses delivered by electrodes to cause the heart muscle chambers (the upper, or atria and/or the lower, or ventricles) to contract and therefore pump blood.
By doing so, this device replaces and/or regulates the function of the electrical conduction system of the heart.
The 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.
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.
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.
