A report on Atrial flutter, Arrhythmia and Atrioventricular node
Atrial flutter (AFL) is a common abnormal heart rhythm that starts in the atrial chambers of the heart.- Atrial flutter
Supraventricular tachycardias include atrial fibrillation, atrial flutter and paroxysmal supraventricular tachycardia.- Arrhythmia
This also protects the ventricles from excessively fast rate response to atrial arrhythmias (see below).- Atrioventricular node
This is the property of the AV node that prevents rapid conduction to the ventricle in cases of rapid atrial rhythms, such as atrial fibrillation or atrial flutter.- Atrioventricular node
Impulses from the atria are conducted to the ventricles through the atrio-ventricular node (AV node).- Atrial flutter
The impulse initially causes both atria to contract, then activates the atrioventricular node (AV node), which is normally the only electrical connection between the atria and the ventricles (main pumping chambers).- Arrhythmia

Atrial fibrillation (AF or A-fib) is an abnormal heart rhythm (arrhythmia) characterized by rapid and irregular beating of the atrial chambers of the heart.
It may also start as other forms of arrhythmia such as atrial flutter that then transform into AF.
These disorganized waves conduct intermittently through the atrioventricular node, leading to irregular activation of the ventricles that generate the heartbeat.
