Which of the following structures is the primary
pacemaker, which sets the normal rate for the heart?
A) Bundle of His
B) Purkinje fibers
C) Sinoatrial node
D) Atrioventricular node - ANSWER-C
Cardiac pacemakers are bundles of nerves that generate
electrical impulses and conduct them to the cardiac cells,
resulting in contraction of the myocardium (heart muscle).

In a normal healthy heart, the sinoatrial (SA) node is the
primary pacemaker that sets the inherent rate for the
heart. The SA node generates electricity at a rate of 60 to
100 electrical discharges per minute; hence the normal
adult heart rate is 60 to 100 beats/min. The atrioventricular
(AV) node serves as the heart's secondary pacemaker; if
the SA node fails, the AV node resumes the pacing
function of the heart, although at a slower rate (40 to 60
beats/min). The bundle of His and Purkinjie fibers, located
within the ventricles, may serve as tertiary pacemakers if
the SA and AV nodes fail; their inherent pacing rate is 20
to 40 beats/min.
The pulmonary arteries carry deoxygenated blood from
the right ventricle to the lungs for reoxygenation.

Your assessment of a middle-aged female with chest
pressure reveals that she is confused, is diaphoretic, and
has a blood pressure of 70/50 mm Hg. In caring for this
patient, it is MOST important for you to:
A) request an ALS unit to respond to the scene.
B) assist her with her nitroglycerin if she has any.
C) reassess her vital signs at least every 5 minutes.
D) prepare for immediate transport to the hospital. -
ANSWER-D
Your patient is in shock, which is most likely the result of
heart failure (cardiogenic shock). Immediate transport to
the closest appropriate hospital is critical. Assess for and
manage problems with airway, breathing, and circulation,

and then get on the road! She needs definitive care that
can be provided only at the hospital. Reassess her vital
signs at least every 5 minutes, but do it en route! If you
can rendezvous with an ALS unit en route, do so.
However, you should not remain at the scene to wait for
them. Nitroglycerin is clearly contraindicated for this
patient; her BP is dangerously low.
Which of the following questions would be MOST
appropriate to ask when assessing a patient with chest
pain?
A) What does the pain feel like?
B) Does the pain radiate to your arm?
C) Would you describe the pain as sharp?
