There are two branches of the bundle of His: the left bundle branch and the right bundle branch, both of which are located along the interventricular septum. The left bundle branch further divides into the left anterior fascicle and the left posterior fascicle. These structures lead to a network of thin filaments known … Se mer The bundle branches, or Tawara branches, are offshoots of the bundle of His in the heart's ventricle. They play an integral role in the electrical conduction system of the heart by transmitting cardiac action potentials from … Se mer When a bundle branch or their fascicles becomes injured (by underlying heart disease, myocardial infarction, or cardiac surgery), it may cease to conduct electrical impulses appropriately, resulting in altered pathways for ventricular depolarization. This condition is … Se mer The bundle branches were separately described by Retzer and Braeunig as early as 1904, but their physiological function remained unclear and … Se mer • Massing GK, James TN (April 1976).

Nettet13. jun. 2016 · Depolarization of the ventricles is delayed, resulting in a wide QRS complex of 0.12 second or greater. The presence of a bundle-branch block (Figures 9-2, 9-3 and 9-4 and Box 9-1) can be recognized by a monitoring lead. Differentiating between right and left bundle-branch block requires a 12-lead electrocardiogram (ECG).
