Premature Junctional Contraction (PJC) -CORRECT ANSWERS -
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 ANSWERS -
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 ANSWERS -
Wide an bizarre QRS complex, greater than 100 beats per minute, absent P waves, no
PRI, can be monomorphic or polymorphic

AV node rate
40-60 bpm -CORRECT ANSWERS –
Prukinje fiber rate
15-40bpm
Accelerated Junctional Rhythm -CORRECT ANSWERS -
regular rhythm, rate 60-100, p waves inverted or occur before during or after QRS, PRI
measured if p before QRS <0.12
