DYSRHYTHMIA COMPREHENSIVE
TEST SCRIPT 2026 QUESTIONS WITH
SOLUTIONS 100% CORRECT.
◍ Junctional Tachycardia. Answer: >60 bpm (ms. K; 150-250)
- KEY: will be regular (consistent)
- AV junction produces a rapid sequence of QRS-T cycles
- p-wave often inverted/buried/follow QRS
◍ Premature Junctional Contraction. Answer: Inverted p wave or
hidden p wave
PRI<0.12 or none
Normal QRS
◍ Supraventricular Tachycardia (SVT). Answer: an abnormal heart
rhythm arising from aberrant electrical activity in the heart; originates
at or above the AV node
◍ First degree heart block. Answer: atrioventricular (AV) block in
which the atrial electrical impulses are delayed by a fraction of a
second before being conducted to the ventricles
◍ 2nd degree heart block type 1 (Wenkebach). Answer: Progressively
longer PR interval until the P wave is not followed by a QPR
, ◍ 2nd Degree Heart Block (Mobitz II). Answer: Rare, but more
serious
Sudden appearance of a nonconducted P-wave
P-waves are nl, but some aren't followed by a QRS complex
PR & RR intervals are constant
◍ 3rd degree heart block. Answer: no obvious correlation between p
and qrs, need pace maker
◍ premature ventricular contraction (PVC). Answer: a ventricular
contraction preceding the normal impulse initiated by the SA node
(pacemaker)
◍ Bigeminy PVC. Answer: every other beat is a PVC
◍ PVC couplets. Answer: PVC occurring in pairs, no adequate C.O.
when this occurs
◍ monomorphic ventricular tachycardia. Answer: presents with wide
QRS complexes of a common shape.
◍ Torsades de pointes. Answer: Rate: 120 - 200 usually
P wave: Obscured by ventricular waves
QRS: Wide QRS - "Twisting of the Points"
Conduction: Ventricular only
Rhythm: Slightly irregular
