Bifascicular block is characterized by right bundle branch block with left anterior fascicular block, or right bundle branch block with left posterior fascicular block on electrocardiography. Complete heart block could be the cause of syncope that is otherwise unexplained if bifascicular block is seen on electrocardiography . [ 1 ]
An intraventricular block is a heart conduction disorder — heart block of the ventricles of the heart. [1] An example is a right bundle branch block, right fascicular block, bifascicular block, trifascicular block. [2] [3]
Second-degree atrioventricular block (AV block) is a disease of the electrical conduction system of the heart. It is a conduction block between the atria and ventricles. The presence of second-degree AV block is diagnosed when one or more (but not all) of the atrial impulses fail to conduct to the ventricles due to impaired conduction.
Myocardial infarction complications may occur immediately following a myocardial infarction (heart attack) (in the acute phase), or may need time to develop (a chronic problem). After an infarction, an obvious complication is a second infarction, which may occur in the domain of another atherosclerotic coronary artery, or in the same zone if ...
Left anterior fascicular block (LAFB) is an abnormal condition of the left ventricle of the heart, [1] [2] related to, but distinguished from, left bundle branch block (LBBB). It is caused by only the left anterior fascicle – one half of the left bundle branch being defective. It is manifested on the ECG by left axis deviation.
First-degree heart block does not require any particular investigations except for electrolyte and drug screens, especially if an overdose is suspected. [5] In comparison to second-degree atrioventricular block, in first-degree block there is an absence of non-conduction or "dropped beats."
In contrast, the latest research focuses on young adults ages 21–25 – an important age group. Chronic diet-associated conditions, like type 2 diabetes or obesity, often take decades to develop ...
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. Only the posterior part of the left bundle branch is involved; Other classifications of bundle branch blocks are; Bifascicular ...
