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.
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]
While heart block is benign for most people, it can be a precursor to more serious heart problems.
First degree AV block does not generally cause any symptoms, but may progress to more severe forms of heart block such as second- and third-degree atrioventricular block. It is diagnosed using an electrocardiogram , and is defined as a PR interval greater than 200 milliseconds. [ 1 ]
Fitzgerald’s case illustrates a dangerous gap in medical care between men and women. While they are equally likely to suffer heart attacks, women are more likely to die from theirs.
Heart block comes in varying degrees and severity. It may be caused by reversible poisoning of the AV node (with drugs that impair conduction) or by irreversible damage to the node. Bradycardias may also be present in the normally functioning heart of endurance athletes or other well-conditioned persons.
