1) the inherent rate of the sa node is ____ bpm.
A) 30-60
B) 40-60
C) 60-100
D) 100-120
ANS:>c
Learning obj.: 1.3
Rationale: the sinoatrial (sa) node, often referred to as the heart's natural pacemaker, has
an inherent rate of 60-100 beats per minute (bpm). It is responsible for initiating the
electrical impulses that regulate the heart's rhythm. When functioning normally, the sa
node sets the pace for the rest of the conduction system.
2) the inherent rate of the av junction is ____ bpm.
A) 20-40
B) 40-60
C) 60-100
D) 100-120
ANS:>b
, Learning obj.: 1.3
Rationale: the av junction, which includes the av node and surrounding tissue, has an
inherent rate of 40-60 bpm. This area serves as a secondary pacemaker when the sa node
fails to generate impulses. Although the rate is slower than that of the sa node, it can take
over the pacing role if necessary.
3) the inherent rate of the ventricle is ____ bpm.
A) 20-40
B) 40-60
C) 60-100
D) 100-120
ANS:>a
Learning obj.: 1.3
Rationale: the ventricles have the slowest inherent rate of 20-40 bpm. When higher
pacemaker sites (such as the sa node or av junction) fail, the ventricles can generate
electrical impulses to maintain a basic heart rate, although the rate is much slower than
normal.
4) the built-in rate of each of the three major areas of the conduction system is referred to
as the ____ rate.
A) fast
B) heart
