When no atrial impulse is conducted through the AV node into
the ventricles, the patient is said to be experiencing which type of
AV block?
a) Third degree
In third degree heart block, two impulses stimulate the heart—one
stimulates the ventricles and one stimulates the atria.
b) First degree
In first degree heart block, all the atrial impulses are conducted
through the AV node into the ventricles at a rate slower than normal.
c) Second degree, type I
In second degree AV block, type I, all but one of the atrial impulses
are conducted through the AV node into the ventricles.
d) Second degree, type II
In second degree AV block, type II, only some of the atrial impulses
are conducted through the AV node into the ventricles.
