  1. Atrioventricular block

    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. The signal travels from the SA node to the ventricles through the atrioventricular node (AV node). In an AV block, this electrical signal is either delayed or completely blocked. When the signal is completely blocked, the ventricles produce their own electrical signal to control the heart rate. The heart rate produced by the ventricles is much slower than that produced by the SA node.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.


  1. atrioventricular block

    Atrioventricular block, also known as a heart block, is a medical condition where the conduction of the electrical signals in the heart is delayed or stopped, resulting in a disruption of the heart's normal rhythm. This condition can occur on various levels of severity depending on where the disruption takes place in the conduction system. It can lead to symptoms such as dizziness, shortness of breath, fatigue, or fainting. In some serious cases, it may require treatment with a pacemaker.


  1. Atrioventricular block

    An atrioventricular block involves the impairment of the conduction between the atria and ventricles of the heart. Under normal conditions, SA node in the atria sets the pace for the heart, and these impulses travel down to the ventricles. In an AV block, this message does not reach the ventricles or is impaired along the way. The ventricles of the heart have their own pacing mechanisms, which can maintain a lowered heart rate in the absence of SA stimulation. The causes of pathological AV block are varied and include ischaemia, infarction, fibrosis or drugs, and the blocks may be complete or may only impair the signaling between the SA and AV nodes. Certain AV blocks can also be found as normal variants, such as in athletes or children, and are benign. Strong vagal stimulation may also produce AV block. The cholinergic receptor types affected are the muscarinic receptors. There are three types: ⁕First degree AV block - PR interval greater than 0.20sec. ⁕Second degree AV block - Type 1: Progressive prolongation of PR interval with dropped beats . Type 2: PR interval remains unchanged prior to the P wave which suddenly fails to conduct to the ventricles.
