Question

question 10 name the type of atrioventricular (av) block in which no electrical impulses reach the ventricles. a first - degree b third - degree c fourth - degree d second - degree

Explanation:

In a third - degree atrioventricular (AV) block, also known as complete heart block, there is a complete dissociation between atrial and ventricular electrical activity, and no electrical impulses from the atria reach the ventricles. First - degree AV block has a prolonged PR interval but all impulses reach the ventricles. Second - degree AV block has some impulses that do not reach the ventricles, but not all. There is no fourth - degree AV block in standard cardiac electrophysiology terminology.

Answer:

B. third - degree
