  2. Right bundle branch block - Wikipedia

    en.wikipedia.org/wiki/Right_bundle_branch_block

    A right bundle branch block (RBBB) is a heart block in the right bundle branch of the electrical conduction system. [1] During a right bundle branch block, the right ventricle is not directly activated by impulses traveling through the right bundle branch. However, the left bundle branch still normally activates the left ventricle.

  3. Bundle branch block - Wikipedia

    en.wikipedia.org/wiki/Bundle_branch_block

    Right bundle branch block, incomplete (IRBBB) or complete (CRBBB) Left bundle branch block, incomplete (iLBBB) or complete (cLBBB) The left bundle branch block can be further sub classified into: Left anterior fascicular block. In this case only the anterior half of the left bundle branch (fascicle) is involved; Left posterior fascicular block ...

  4. Tachycardia-dependent bundle branch block - Wikipedia

    en.wikipedia.org/wiki/Tachycardia-dependent...

    Tachycardia-dependent bundle branch block (TDBBB) can affect either ventricle in the heart, and occurs when the heart's rate of contraction reaches an elevated level and becomes uncoupled from the heart's refractory period (the time it takes for a cardiac cell to "reset" for future contraction).

  5. Electrocardiography - Wikipedia

    en.wikipedia.org/wiki/Electrocardiography

    Normal 12-lead ECG A 12-lead ECG of a 26-year-old male with an incomplete right bundle branch block (RBBB). The overall goal of performing an ECG is to obtain information about the electrical functioning of the heart.

  6. Heart block - Wikipedia

    en.wikipedia.org/wiki/Heart_block

    Infra-Hisian blocks may occur at the left or right bundle branches ("bundle branch block") or the fascicles of the left bundle branch ("fascicular block" or "Hemiblock"). SA and AV node blocks are each divided into three degrees, with second-degree blocks being divided into two types (written either "type I or II" or "type 1 or 2").

  7. Intraventricular block - Wikipedia

    en.wikipedia.org/wiki/Intraventricular_block

    Intraventricular conduction delay seen in precordial/chest leads with QRS duration 100 ms. An EKG of a 25-year-old male. Intraventricular conduction delays (IVCD) are conduction disorders seen in intraventricular propagation of supraventricular impulses resulting in changes in the QRS complex duration or morphology, or both.

    en.wikipedia.org/wiki/Bundle_branches

    The bundle branches were separately described by Retzer and Braeunig as early as 1904, but their physiological function remained unclear and their role in the electrical conduction system of the heart remained unknown until Sunao Tawara published his monograph on Das Reizleitungssystem des Säugetierherzens (English: The Conduction System of the Mammalian Heart) in 1906.
