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)

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
