Atrioventricular block ( AV block) is a type of heart block that occurs when the electrical signal traveling from the atria, or the upper chambers of the heart, to ventricles, or the lower chambers of the heart, is impaired. Normally, the sinoatrial node (SA node) produces an electrical signal to control the heart rate.

Since its first description by Hays in England in 1906, second-degree atrioventricular (AV) block has been a fascinating clinical entity, mainly due to obscure points regarding its diagnosis that emanate from misconceptions and errors regarding its proper definition.1–3 The practicing clinician should be aware of the following points that may assist a proper diagnosis and, consequently Electrocardiographic Holter recordings at 12.5 mm/s, 3 consecutive strips.

Atrioventricular block (AV block) is characterized by an interrupted or delayed conduction between the atria and the ventricles. There are three degrees of AV block, categorized according to the extent of the delay or interruption. First-degree blocks are identifiable on ECG by a prolonged PR interval.

First-degree blocks are identifiable on. ECG. by a prolonged. Atrioventricular (AV) Block A normal heartbeat starts with an electrical impulse originating within sinoatrial (SA) node, also called the Pacemaker.

Treatment of AV block in the acute setting Treatment in the acute setting is directed at managing bradycardia and reduced cardiac output. Start with atropine 0.5 mg iv (may be repeated). Atropine will have effect if the block is located in the AV node.

Second-degree atrioventricular blocks are occasional non-conducted P waves with prolonged RR intervals. There are two types under this classification.

The passage of the electrical message travels at a different speed which can make the heart beat more slowly. There are different levels of AV block – first degree, second degre Atrioventricular (AV) block can be described by degree (based on ECG appearance) or by anatomic level of block. The degree of AV block or anatomic level of block does not necessarily correlate with the severity of subsequent symptoms.
