n the T wave te originating -flutter with 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

• 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 withi

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)

7. Atrial Fibrillation (A-Fib): an irregular and often very fast heart ra

from abnormal conduction in the atria

8. Atrial Flutter: irregular beating of the atria; often described as "a

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

• normal sinus rhythm: heart rhythm originating in the sinoatrial node with a rate

in patients at rest of 60 to 100 beats per minute

12. Supraventricular Tachycardia (SVT): an abnormal heart rhyth

aberrant electrical activity in the heart; originates at or above the AV

13. First degree heart block: atrioventricular (AV) block in which the

cal impulses are delayed by a fraction of a second before being co ventricles

14. 2nd degree heart block type 1 (Wenkebach): Progressively lo

val until the P wave is not followed by a QPR

15. 2nd Degree Heart Block (Mobitz II): Rare, but more serious

Sudden appearance of a nonconducted P-wave P-waves are nl, but some aren't followed by a QRS complex PR & RR intervals are constant

16. 3rd degree heart block: no obvious correlation between p and q

maker

17. premature ventricular contraction (PVC): a ventricular contra

ing the normal impulse initiated by the SA node (pacemaker)

18. Bigeminy PVC: every other beat is a PVC

19. PVC couplets: PVC occurring in pairs, no adequate C.O. when

20. monomorphic ventricular tachycardia: presents with wide Q

of a common shape.

• Torsades de pointes: Rate: 120 - 200 usually

P wave: Obscured by ventricular waves

QRS: Wide QRS - "Twisting of the Points"

Conduction: Ventricular only

Rhythm: Slightly irregular

22. Ventricular fibrillation (V-fib): abnormal heart rhythm which re

ing of ventricles

23. Idioventricular Rhythm: <40>

*looks like vtach but slow*

• no P waves (from vent foci)
• Wide QRS

11. Premature Junctional Contraction: Inverted p wave or hidde

PRI<0>

in cases of

(serious, death like rhythm)

• called "dying heart" rhythm...occasional ventric beat b4 death (asystole)
• Accelerated Idioventricular Rhythm: Rate: 50 - 100 usually (usually slow)

P wave: Obscured by ventricular waves (occur during ventricular contraction) - SA node slower than faster ventricular pacing than should be

QRS: Wide QRS

Conduction: Ventricular only

Rhythm: Regular

• benign rhythm that is sometimes seen during acute MI or early after reperfusion.
• Rarely sustained, does not progress to vfib, rarely requires treatment

25. asystole: absence of contractions of the heart

26. Failure to capture (pacemaker):

27. failure to sense (pacemaker):

28. Atrial paced rhythm: spike before P wave

29. Ventricular paced rhythm: ventricular contractions which occur

complete heart block.
