BASIC DYSRHYTHMIA-RELIAS
normal sinus rhythm - CORRECT ANSWER-heart rhythm originating in the
sinoatrial node with a rate in patients at rest of 60 to 100 beats per minute
Sinus Arrhythmia - CORRECT ANSWER-Appearance is ALMOST NORMAL:
Respiratory - Circulatory interaction
Rate INCREASES with INSPIRATION (IN=IN)
Sinus Bradycardia - CORRECT ANSWER-<60
normal sinus rhythm
Sinus Tachycardia - CORRECT ANSWER->100 (100-150)
normal sinus rhythm
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
Sinus Arrest/Pause - CORRECT 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) - CORRECT ANSWER-an irregular and often very fast
heart rate originating from abnormal conduction in the atria
Atrial Flutter - CORRECT ANSWER-irregular beating of the atria; often described
as "a-flutter with 2 to 1 block or 3 to 1 block"
Junctional Rhythm - CORRECT 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)
Junctional Tachycardia - CORRECT 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 - CORRECT ANSWER-Inverted p wave or
hidden p wave
PRI<0.12 or none
Normal QRS
Supraventricular Tachycardia (SVT) - CORRECT ANSWER-an abnormal heart
rhythm arising from aberrant electrical activity in the heart; originates at or
above the AV node
normal sinus rhythm - CORRECT ANSWER-heart rhythm originating in the
sinoatrial node with a rate in patients at rest of 60 to 100 beats per minute
