The heart rate produced by the ventricles is much slower than that produced by the SA node. [1] Some AV blocks are benign, or normal, in certain people, such as in athletes or children. Other blocks are pathologic, or abnormal, and have several causes, including ischemia, infarction, fibrosis, and drugs.
Beta blockers: To block the effects of certain hormones on the heart to slow the heart rate. C alcium Channel Blockers: Help slow the heart rate by blocking the number of electrical impulses that pass through the AV node into the lower heart chambers (ventricles).
Heart block should not be confused with other conditions, which may or may not be co-occurring, relating to the heart and/or other nearby organs that are or can be serious, including angina (heart-related chest pain), heart attack (myocardial infarction), any type of heart failure, cardiogenic shock or other types of shock, different types of ...

Heart block describes a type of arrhythmia, or abnormal rhythm, that happens when the electrical signal gets held up and delayed, or blocked entirely at some point along the conduction system. These blocks or delays usually happen because of some sort of damage or fibrosis to the electrical conduction system, the pathways that conduct the ...
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.
