Question:
● 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



Question:
● 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



Question:
● 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



Question:
● 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



Question:
● 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



Question:
● 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



Question:
● 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



Question:
● 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



Question:

, ● 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



Question:
● 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"



Question:
● After placing the leads on the patient, you see artifact on the monitor, what are some reasons this
could be happening?

Answer:
Leads are not secure on the patient Patient may be moving ● On ECG paper. the big box is ____
mV by _____ sec



Question:
the little box is ____ mV by _____ sec

Answer:
Big box = 0.5 mV by 0.2 sec Little box = 0.1 mV by 0.04 sec



Question:
● The _______________ line signifies no electrical discharge or repolarization. It is the line that
runs horizontally across the ECG strip.

Answer:
Isoelectric
