The left bundle branch is subdivided into the following two fascicles: (1)the anterior (anterosuperior) fascicle, whichdelivers the electrical impulse to the anterior wall of the left ventricle; (2)the posterior (posteroinferior) fascicle, whichdelivers the electrical impulse to the posterior and inferiorwalls of the left ventricle. In conclusion, among patients with left bundle branch block, those with left axis deviation have a greater incidence of myocardial dysfunction, a more advanced conduction disease, and greater cardiovascular damage which can lead to mortality (if not properly treated immediately) than those with a normal axis. official website and that any information you provide is encrypted Bifascicular block is a combination of right bundle branch block and either left anterior fascicular . It then spreads down the bundle of Hisand then Purkinje fibres to cause ventricular contraction. Normal variation, pre-excitation syndrome, conduction defects, inferior wall myocardial infarction, congenital heart disease, ventricular ectopic rhythms, emphysema, mechanical shift, high potassium levels, paced rhythm, and thickened left ventricle are just a few of the causes. As a result of these changes, complications of left ventricular hypertrophy include: Axis deviation, while not a dangerous finding in and of itself, may indicate a serious underlying condition. Blockage of the left posterior fascicle would lead to activation of the anterior portion of the left ventricle followed by activation of the rest of the ventricle in a superior to inferior direction and directed towards the right. bundle branch block is well recognized. The normal variation that causes LAD is a physiologic alteration that occurs with age. The symptoms of left axis deviation are determined by the underlying reason.
