Basic Dysrhythmia-Relias
Assesment Test/Latest

Answers
normal sinus rhythm - -heart rhythm originating in the
sinoatrial node with a rate in patients at rest of 60 to 100
beats per minute
-Sinus Arrhythmia - -Appearance is ALMOST NORMAL:
Respiratory - Circulatory interaction
Rate INCREASES with INSPIRATION (IN=IN)
-Sinus Bradycardia - -<60
normal sinus rhythm
-Sinus Tachycardia - ->100 (100-150)
normal sinus rhythm
-Premature Atrial Contraction (PAC) - -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 - -- 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!
