SHARP EKG
Maximize your success on the SHARP EKG (Electrocardiography)
Exam with focused preparation that strengthens your
understanding of cardiac rhythms, waveform analysis,
ischemia/infarction patterns, and the clinical implications of
common and complex arrhythmias. It is specifically designed for
nurses, paramedics, and cardiovascular technicians to validate
their proficiency in electrocardiogram analysis and patient
management.
What is a paroxysmal junctional tachycardia? .......
ANSWER ....... ✓ ✓ A arrhythmia originating in the AV
junction with a heart rate exceeding 100 bpm
What is a first degree heart block? ....... ANSWER ....... ✓ ✓
The PR interval is delayed longer than normally >0.20
, Page 2 of 55
Does a first degree heart block require treatment? .......
ANSWER ....... ✓ ✓ No treatment
What is a second degree Second Degree AV block Type 1
(Mobitz 1 or Wenckebach)? ....... ANSWER ....... ✓ ✓ The
sinus impulse takes longer to travel through the AV node
which is seen by a progressively lengthening PR interval from
beat to beat eventually dropping a QRS
Which drug could help a Second Degree AV Block Type 1?
....... ANSWER ....... ✓ ✓ Atropine
What is a Second Degree AV Block Type 2? ....... ANSWER
....... ✓ ✓ There is more than 1 P-wave before each QRS
complex with only one of the impulses being conducted to
the ventricles
-PR interval consistent
Is a Mobitz II a result of a vagal tone or drug toxicity? .......
ANSWER ....... ✓ ✓ No
, Page 3 of 55
Why are Second Degree AV blocks type 2 dangerous? .......
ANSWER ....... ✓ ✓ Can potentially lead to a Third Degree
AV Block or asystole
What is a Third Degree AV block? ....... ANSWER ....... ✓ ✓
Atria and ventricles beat independently of each other
-P waves occur at regular intervals across the rhythm strips
but have no relationship with QRS's
How does the QRS appear in a Third Degree AV block if the
block is in the level of the bundle branches? ....... ANSWER
....... ✓ ✓ Widened
How many muscle layers of the heart are there and what are
they? ....... ANSWER ....... ✓ ✓ 1. Endocardium
2. Myocardium
3. Epicardium/pericardium
What is the endocardium? ....... ANSWER ....... ✓ ✓
innermost layer of the heart
, Page 4 of 55
What is the myocardium? ....... ANSWER ....... ✓ ✓
Muscular layer that comprises most of the heart wall
What is the epicardium/pericardium? ....... ANSWER .......
✓ ✓ Compromises the sac around the heart; provides
protection to the heart
What is the tricuspid valve? ....... ANSWER ....... ✓ ✓
separates the right atrium from the right ventricle
What is the pulmonic valve? ....... ANSWER ....... ✓ ✓
Separating right ventricle from the pulmonary arteries
What is the mitral valve? ....... ANSWER ....... ✓ ✓ valve
between the left atrium and the left ventricle.
What is the aortic valve? ....... ANSWER ....... ✓ ✓ valve
between left ventricle and aorta
