Electrical Conduction System of The Heart

Electrical Conduction System Of The Heart

Latin systema conducens cordis

The normal intrinsic electrical conduction of the heart allows electrical propagation to be transmitted from the Sinoatrial Node through both atria and forward to the Atrioventricular Node. Normal/baseline physiology allows further propagation from the AV node to the ventricle or Purkinje Fibers and respective bundle branches and subdivisions/fascicles. Both the SA and AV nodes stimulate the Myocardium. Time ordered stimulation of the myocardium allows efficient contraction of all four chambers of the heart, thereby allowing selective blood perfusion through both the lungs and systemic circulation.

Famous quotes containing the words electrical, system and/or heart:

    Few speeches which have produced an electrical effect on an audience can bear the colourless photography of a printed record.
    Archibald Philip Primrose, 5th Earl Rosebery (1847–1929)

    How natural that the errors of the ancient should be handed down and, mixing with the principles and system which Christ taught, give to us an adulterated Christianity.
    Olympia Brown (1835–1900)

    This is the hope of many adolescent girls—to capture a parent’s heart with love for them as they are, as people. They reject the notion of being loved just because they are the child of the parent. They want the parent to fall in love with them all over again, because being new, they deserve a new love.
    Terri Apter (20th century)
