RELIAS BASIC DYSRHYTHMIA
1. normal sinus rhythm: heart rhythm originating in the sinoatrial node with a rate
in patients at rest of 60 to 100 beats per minute
2. Sinus Arrhythmia: Appearance is ALMOST NORMAL:
Respiratory - Circulatory interaction
Rate INCREASES with INSPIRATION (IN=IN)
3.Sinus Bradycardia:
<60 normal sinus
rhythm
4.Sinus Tachycardia: >100
(100-150) normal sinus rhythm
5.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
PRI: measures between .12-.20 seconds and canwave
be
prolonged; can be different from other complexes
QRS: <.12 seconds
6.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) te
7.Atrial Fibrillation (A-Fib): an irregular and often very originating
fast heart ra from abnormal conduction in the atria
8.Atrial Flutter: irregular beating of the atria; often lutter with 2
described as "a-f 1 block or 3 to 1 block" to
9.Junctional Rhythm: 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: >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

, 11.Premature Junctional Contraction: Inverted p wave p
or hidden PRI<0.12 or none wave
Normal QRS
12.Supraventricular Tachycardia (SVT): an abnormal arising
heart rhythm aberrant electrical activity in the heart; from ode
originates at or above the AV n
