1

What is the order of Heart Rhythm Analysis?

Calculate Rate
Determine Regularity
Assess the P Waves
Determine PR Interval
Determine QRS Duration

2

What is Bradycardia?

HR < 60 bpm

3

What is Normal Heart Rate?

HR = 60 - 100 bpm

4

What is Tachycardia?

HR > 100 bpm

5

What is the normal for PR Intervals?

0.12 - 0.2 seconds (3 - 5 boxes)

6

What is the normal for QRS durations?

0.04 - 0.12 (1 - 3 boxes)

7

What are the characteristics of Sinus Arrhythmia?

P waves normal, upright, and identical
P waves before every QRS
PR Interval between 0.12 - 0.2 seconds
QRS complexes are identical
QRS duration between 0.04 - 0.1 seconds
R-R interval varies
HR: 40 - 100 bpm

8

What are the main concepts of Sinus block?

P waves normal, upright, and identical
P waves before every QRS
PR Interval between 0.12 - 0.2 seconds
QRS complexes are identical
QRS duration between 0.04 - 0.1 seconds
R-R interval is regular, but occasionally QRS complex is missing
HR: 60 - 100 bpm

9

What are the main concepts of Sinus Arrest?

When sinus block lasts for more than 3 seconds

10

What is Sick Sinus Syndrome (SSS)?

Tachybrady

11

What is a Premature Atrial Contraction?

P wave comes early, and its shape is slightly different

12

What are the main concepts of Paroxysmal Atrial Tachycardia?

HR: 150 - 250 bpm
Changes the shape of the P wave

13

What are the main concepts of Atrial Flutter?

Sawtooth pattern
Atria firing 200 - 300 times a minute
Multiple P waves per QRS complex
QRS are regular

14

What are the names for the different PACs?

Single PAC
Atrial Bigeminy: every other
Atrial Trigeminy: every third
Atrial Quadrigeminy: every fourth
Pair: 2 in a row
Triplet: 3 in a row
Run: More than 3 in a row

15

What are the characteristics of Atrial Fibrillation?

No clear P waves
Irregular
Wavy Baseline

16

What are the characteristics of Wandering Atrial Pacemakers?

P-P Interval varies
P waves change shape and direction
Atrial rate less tan 100 bpm

17

What are the characteristics of Supraventricular Tachycardia?

Narrow/Normal QRS complex
No P waves
What can be used to call PAT, PJT, and A-Fib

18

What are the characteristics of a Junctional Escape?

Late, narrow QRS
Inverted P wave (if there)
Rate: 40 - 60 (If greater = accelerated)
Two is a pair and three is a junctional rhythm

19

What are the characteristics of a Premature Junctional Contraction?

Early, narrow RS
P wave is inverted (if there)
Two is a pair, three is a run of Paroxysmal Tachycardia
Usually inverted compared to PAC

20

What are the characteristics of Accelerated Idiojunctional Rhythms?

Same as a junctional escape, but the rate is faster than 60 bpm

21

What are the characteristics of Ventricular Escape Beats?

Wide QRS
No P wave
Rate is 20 - 40 bpm
Considered Accelerated Idioventricular Rhythm if the rate is between 41 - 100
Agonal: rate is < 20 bpm

22

What are the characteristics of Premature Ventricular Contractions?

Wide, bizarre QRS complexes
Uniform: premature beats look alike
Multiform: look different

23

What are the characteristics of Ventricular Tachycardia?

Odd, wide QRS complexes
No real P waves
Fairly regular

24

What are the characteristics of Ventricular Fibrillation?

Constant Waves

25

What are the characteristics of a Pacer Rhythm?

Pacer spike at the P wave

26

What are the characteristics of Ventricular Standstill?

Only P waves

27

What is asystole?

Flat line

28

What are the characteristics of a Bundle-Branch Block?

Longer QRS complex
Wide S wave (leads I, V5, and V6)
Bunny ears

29

What is a First Degree A-V Block?

P-R Interval > .20 seconds (more than 5 boxes)
P-R Intervals are all equal

30

What is a Wenckebach (Mobitz I) Second Degree Block?

P-R interval gradually increases until QRS is completely dropped; pattern repeats

31

What is a Mobitz II Second Degree Block?

P-R's are equal
Multiple dropped

32
