Question

Quizplus · Accepted Answer

Third-degree heart block, also known as complete heart block, is characterized by a complete dissociation between the atria and ventricles. This means that no electrical impulses originating from the atria reach the ventricles, resulting in an independent rhythm in the two chambers. This can lead to a potentially life-threatening situation and may require urgent intervention. First-degree, second-degree, fourth-degree, and fifth-degree heart blocks are different types of AV blocks but do not involve a complete dissociation between the atria and ventricles.
