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
