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 wave
PRI: measures between .12-.20 seconds and can 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)

, 8. Atrial Flutter: irregular beating of the atria; often described as "a-flutter with
2 to 1 block or 3 to 1 block"
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
