Question

Quizplus · Accepted Answer

AV dissociation occurs when there is a lack of synchronization between atrial and ventricular contractions, resulting in independent rhythm between the two. This is most commonly seen in third-degree (complete) heart blocks where there is a complete blockage in the conduction pathway between the atria and ventricles, leading to independent electrical activity in both chambers. Second-degree and first-degree blocks may show some degree of AV dissociation, but it is not as pronounced as in third-degree blocks. Fourth-degree blocks do not exist and are not a recognized term in cardiology.
