Basic Dysrhythmia-Relias
1. normal sinus rhythm <Ans> heart rhythm originating in the sinoatrial node
with a rate in patients at rest of 60 to 100 beats per minute
2. Sinus Arrhythmia <Ans> Appearance is ALMOST
NORMAL Respiratory - Circulatory interaction
Rate INCREASES with INSPIRATION (IN=IN)
3. Sinus
Bradycardia<Ans> <60
normal sinus rhythm
4. Sinus Tachycardia <Ans> >100
(100-150) normal sinus rhythm
5. Premature Atrial Contraction (PAC) <Ans> Heart Rate: Depends on
underlying rhythm
Regularity <Ans> Interrupts the regularity of underlying rhythm
P-Wave <Ans> can be flattened, notched, or unusual. May be hiddenthe
within
T wave
PRI <Ans> measures between .12-.20 seconds and can be
prolonged; can be different from other complexes
QRS <Ans> <.12 seconds
6. Sinus Arrest/Pause <Ans> - SA node doesn't fire
- notice absence of P-wave for a complete cycle (a missed cycle)
1/7
te originating
, length of pause ` multiple of normal rate (block)
7. Atrial Fibrillation (A-Fib) <Ans> an irregular and often very fast
heart ra from abnormal conduction in the atria lutter with 2 to
8. Atrial Flutter <Ans> irregular beating of the atria; often
described as "a-f 1 block or 3 to 1 block"
9. Junctional Rhythm <Ans> 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)
10. Junctional Tachycardia <Ans> >60 bpm (ms. K; 150-250)
- KEY <Ans> will be regular (consistent)
- AV junction produces a rapid sequence of QRS-T cycles
- p-wave often inverted/buried/follow QRS
11. Premature Junctional Contraction <Ans> Inverted p wave or p wave
hidden PRI<0.12 or none
Normal QRS
12. Supraventricular Tachycardia (SVT) <Ans> an abnormal heart arising from
ode
rhythm aberrant electrical activity in the heart; originates at or above
