SHARP ECG TEST (LATEST UPDATE 2025/26)
A+GRADED ||BRAND NEW!!!
tachycardia and bradycardia -CORRECT ANSWER >100 bpm
<60 bpm
Bigeminy -CORRECT ANSWER every other complex is a PVC
Trigeminy -CORRECT ANSWER pattern in which every third complex is a premature
beat
Premature Junctional Contraction (PJC) -CORRECT 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) -CORRECT 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 -CORRECT 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 -CORRECT ANSWER 60-100 bpm
AV node rate -CORRECT ANSWER 40-60 bpm
Prukinje fiber rate -CORRECT ANSWER 15-40bpm
Accelerated Junctional Rhythm -CORRECT ANSWER regular rhythm, rate 60-100, p
waves inverted or occur before during or after QRS, PRI measured if p before QRS
<0.12
