CARDIAC QUESTIONS AND SOLUTIONS
VERIFIED GRADED A+
●● A patient comes into the ER complaining of chest pain that radiates
to the left shoulder. You do a 12 lead EKG and see ST elevation in leads
*V1-V4*. Where in the heart is this patients MI?
Answer: Anterior - Left Anterior Descending Artery
●● A patient comes into the ER complaining of chest pain that radiates
to the jaw. You do a 12 lead EKG and see ST elevation in leads *I, aVL,
V5, and V6*. Where in the heart is this patients MI?
Answer: Lateral - Left Circumflex (LCX) Artery
●● A patient comes into the ER complaining of chest pain that radiates
to the middle of the upper back. You do a 12 lead EKG and see ST
depression and tall R waves in leads *V1 and V2*. Where in the heart is
this patients MI?
Answer: Posterior - RCA and/or LCX Artery
●● List the flow of blood through the heart:
Answer: Superior/Inferior vena cava—>
,right atrium —> [TRICUSPID valve]
right ventricle —> [PULMONARY valve]
lungs via pulmonary arteries —>
from lungs back to the heart via pulmonary veins—>
left atrium —> [MITRAL valve]
left ventricle —> [AORITC valve]
aorta
●● True or false: The *pulmonary artery is the only artery in the body
that carries deoxygenated blood*, and the *pulmonary vein is the only
vein in the body that carries oxygenated blood*.
Answer: TRUE
●● The SA node is the *natural pacemaker of the heart* and is paced at
_________ beats per minute. The SA node *stimulates the heart's atria to
contract* pushing blood into the ventricles (ATRIAL
DEPOLARIZATION).
Answer: 60-100
●● The AV node is found above the ventricles, towards the bottom of the
atria and is paced at _________ beats per minute. The AV node *"holds"
the impulse sent from the SA node, allowing the ventricles to fill. *
Answer: 40-60
, ●● What are the roles of the bundle of HIS and bundle branches?
Answer: Stimulates ventricles to contract, pushing blood from the
ventricles to the body
●● If the SA and AV node fail the ____________________ can initiate a
heartbeat.
Answer: Purkinje fibers
Pace is *20-40* beats per minute
Allows the ventricles to have a synchronized contraction
●● When placing a cardiac monitor, or 5 lead ECG, where is the
location of V1?
Answer: Right sternal border, intercostal space 4 (brown lead)
Other 4 leads (limbs):
White = right shoulder/arm
Black = left shoulder/arm
Green = right leg
Red = left leg
Memory trick: "Smoke over fire" and "clouds over grass"
