RELIAS DYSRHYTHMIA REVIEW QUESTION
SET WITH ACCURATE ANSWERS
◉ Sinus Arrhythmia
Answer: Appearance is ALMOST NORMAL:
Respiratory - Circulatory interaction
Rate INCREASES with INSPIRATION (IN=IN)
◉ Sinus Bradycardia
Answer: <60
normal sinus rhythm
◉ Sinus Tachycardia
Answer: >100 (100-150)
normal sinus rhythm
◉ Premature Atrial Contraction (PAC)
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
◉ Sinus Arrest/Pause
Answer: - 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)
Answer: an irregular and often very fast heart rate originating
from abnormal conduction in the atria
◉ Atrial Flutter
Answer: irregular beating of the atria; often described as "a-
flutter with 2 to 1 block or 3 to 1 block"
◉ Junctional Rhythm
Answer: 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)
