BASIC DYSRHYTHMIA-RELIAS LATEST REAL EXAM QUESTIONS
& VERIFIED ANSWERS (2026) – PASS GUARANTEED
Sinus Arrest/Pause
- SA node doesn't fire
- notice absence of P-wave for a complete cycle (a missed cycle)
length of pause ≠ multiple of normal rate (block)
Atrial Fibrillation (A-Fib)
an irregular and often very fast heart rate originating from abnormal conduction
in the atria
Atrial Flutter
irregular beating of the atria; often described as "a-flutter with 2 to 1 block or 3 to
1 block"
Junctional Rhythm
40-60 Regular!
-impulse from AV node w/ retro/antegrade transmission
- P wave often inverted/buried/follow QRS
- slow rate
- narrow QRS (not wide like ventricular)
Junctional Tachycardia
>60 bpm (ms. K; 150-250)
- KEY: will be regular (consistent)
, 2
- AV junction produces a rapid sequence of QRS-T cycles
- p-wave often inverted/buried/follow QRS
Premature Junctional Contraction
Inverted p wave or hidden p wave
PRI<0.12 or none
Normal QRS
Supraventricular Tachycardia (SVT)
an abnormal heart rhythm arising from aberrant electrical activity in the heart;
originates at or above the AV node
First degree heart block
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)
Progressively longer PR interval until the P wave is not followed by a QPR
2nd Degree Heart Block (Mobitz II)
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
no obvious correlation between p and qrs, need pace maker
premature ventricular contraction (PVC)
a ventricular contraction preceding the normal impulse initiated by the SA node
(pacemaker)
