SHARP ECG TEST EXAM WITH
GUARANTEED CORRECT ANSWERS
Tachycardia and bradycardia - Accurate Answer✅✅>100 bpm
<60 bpm
Bigeminy - Accurate Answer✅✅every other complex is a PVC
Trigeminy - Accurate Answer✅✅pattern in which every third complex is a
premature beat
Premature Junctional Contraction (PJC) - Accurate Answer✅✅Rate: Normal or
accelerated
P wave: inverted or absent
QRS: normal
Conduction: normal
Rhythm: irregular: pics occur early in cycle of baseline rhythm
-an ectopic pacemaker in the AV Junction produces PJC's
-may occur in heatlhy or diseased hearts
-if occasional, insignificant
Premature Atrial Contraction (PAC) - Accurate Answer✅✅Heart Rate: Depends
on underlying rhythm
Regularity: Interrupts the regularity of underlying rhythm
P-Wave: can be flattened, notched, or unusual. May be hidden within the T wave
, PRI: measures between .12-.20 seconds and can be prolonged; can be different
from other complexes
QRS: <.12 seconds
Characteristics of Ventricular Tachycardia - Accurate Answer✅✅Wide an bizarre
QRS complex, greater than 100 beats per minute, absent P waves, no PRI, can be
monomorphic or polymorphic
SA node rate - Accurate Answer✅✅60-100 bpm
AV node rate - Accurate Answer✅✅40-60 bpm
Prukinje fiber rate - Accurate Answer✅✅15-40bpm
Accelerated Junctional Rhythm - Accurate Answer✅✅regular rhythm, rate 60-
100, p waves inverted or occur before during or after QRS, PRI measured if p
before QRS <0.12
AV Blocks - Accurate Answer✅✅AV blocks are identified as a delay or
interruption of the electrical impulse conduction beyond the AV node. It is
evaluated by measuring the PR interval in ECG traces. THE PR INTERVAL IS
THE KEY OF DIFFERENTIATION AND CLASSIFICATION OF THE AV
BLOCKS!
First degree AV block - Accurate Answer✅✅prolonged PR interval
Second Degree AV block type 1 - Accurate Answer✅✅AKA Wenckebach
Results from a cyclical and progressive conduction delay through the AV junction.
