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)

    In nothing was slavery so savage and relentless as in its attempted destruction of the family instincts of the Negro race in America. Individuals, not families; shelters, not homes; herding, not marriages, were the cardinal sins in that system of horrors.
    Fannie Barrier Williams (1855–1944)

    He teaches me to set my heart on nothing. He detaches my mind from friends and relations; and I could watch on as brother, children, mother, and wife all died, and not care in the least.
    Molière [Jean Baptiste Poquelin] (1622–1673)
