2. Sinus Arrhythmia: Appearance is ALMOST NORMAL: Respiratory - Circulatory interaction
Rate INCREASES with INSPIRATION (IN=IN)
3. Sinus Bradycardia:
... [Show More] <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 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
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.
21. 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
(serious, death like rhythm)
- called "dying heart" rhythm...occasional ventric beat b4 death (asystole)
24. 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 bloc [Show Less]
