  2. Cardiac conduction system - Wikipedia

    en.wikipedia.org/wiki/Cardiac_conduction_system

    The conduction system consists of specialized heart muscle cells, situated within the myocardium. [3] There is a skeleton of fibrous tissue that surrounds the conduction system which can be seen on an ECG. Dysfunction of the conduction system can cause irregular heart rhythms including rhythms that are too fast or too slow.

  3. Anatomy of the human heart - Wikipedia

    en.wikipedia.org/wiki/Anatomy_of_the_human_heart

    The heart is a muscular organ situated in the mediastinum.It consists of four chambers, four valves, two main arteries (the coronary arteries), and the conduction system. The left and right sides of the heart have different functions: the right side receives de-oxygenated blood through the superior and inferior venae cavae and pumps blood to the lungs through the pulmonary artery, and the left ...

  4. Cardiac physiology - Wikipedia

    en.wikipedia.org/wiki/Cardiac_physiology

    Transmission of a cardiac action potential through the heart's conduction system. It is not very well known how the electric signal moves in the atria. It seems that it moves in a radial way, but Bachmann's bundle and coronary sinus muscle play a role in conduction between the two atria, which have a nearly simultaneous systole.

  5. Electrocardiography - Wikipedia

    en.wikipedia.org/wiki/Electrocardiography

    The study of the conduction system of the heart is called cardiac electrophysiology (EP). An EP study is performed via a right-sided cardiac catheterization : a wire with an electrode at its tip is inserted into the right heart chambers from a peripheral vein, and placed in various positions in close proximity to the conduction system so that ...

  6. Cardiovascular physiology - Wikipedia

    en.wikipedia.org/wiki/Cardiovascular_physiology

    Cardiovascular physiology is the study of the cardiovascular system, specifically addressing the physiology of the heart ("cardio") and blood vessels ("vascular").. These subjects are sometimes addressed separately, under the names cardiac physiology and circulatory physiology.

  7. Cardiac action potential - Wikipedia

    en.wikipedia.org/wiki/Cardiac_action_potential

    In the heart's conduction system electrical activity that originates from the sinoatrial node (SAN) is propagated via the His-Purkinje network, the fastest conduction pathway within the heart. The electrical signal travels from the sinoatrial node, which stimulates the atria to contract, to the atrioventricular node (AVN) , which slows down ...

  8. Bundle of His - Wikipedia

    en.wikipedia.org/wiki/Bundle_of_His

    The bundle of His (BH) [1]: 58 or His bundle (HB) [1]: 232 (/ h ɪ s / "hiss" [2]) is a 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 ...

  9. Bachmann's bundle - Wikipedia

    en.wikipedia.org/wiki/Bachmann's_bundle

    In the heart's conduction system, Bachmann's bundle (also called the Bachmann bundle or the interatrial band) [1] is a branch of the anterior internodal tract that resides on the inner wall of the left atrium. It is a broad band of cardiac muscle that passes from the right atrium, between the superior vena cava and the ascending aorta. [2]
