WebJul 27, 2024 · The interatrial conduction pathway, also called Bachmann’s bundle, refers to a preferential pathway of specialized cardiomyocytes that facilitate the conduction of impulses between the atria. The pathway … WebBundle branch block: The left and the right bundle branch consists of Purkinje fibers which spread out into the ventricular myocardium. The Purkinje network enables fast impulse conduction so that the action potential can be delivered to the whole myocardium at the same time (approximately).

WebAfter the signal leaves the AV node it travels along a pathway called the bundle of His (3) and into the right and left bundle branches (4, 5). The signal travels across the heart’s ventricles causing them to contract, pumping blood to the lungs and the body. This signal is recorded as the QRS waves on the ECG. 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 known as a bundle branch block. See more 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 … See more 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 … See more 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 … See more • Massing GK, James TN (April 1976).

WebLeft bundle branch area pacing (LBBAP) has emerged as a novel pacing modality which aims to capture the left bundle branch area and avoids the detrimental effects of right ventricular pacing. Current approaches for LBBAP have been developed using lumen-less pacing leads (LLL).
