Answer 12

HR: 150 - 250 bpm

Changes the shape of the P wave

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

Answer 14

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

Answer 16

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

Question 17

What are the characteristics of Supraventricular Tachycardia?

Answer 17

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

Question 18

What are the characteristics of a Junctional Escape?

Answer 18

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

Question 19

What are the characteristics of a Premature Junctional Contraction?

Answer 19

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

Question 20

What are the characteristics of Accelerated Idiojunctional Rhythms?

Answer 20

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

Question 21

What are the characteristics of Ventricular Escape Beats?

Answer 21

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

Question 22

What are the characteristics of Premature Ventricular Contractions?

Answer 22

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

Question 23

What are the characteristics of Ventricular Tachycardia?

Answer 23

Odd, wide QRS complexes
No real P waves
Fairly regular

Question 24

What are the characteristics of Ventricular Fibrillation?

Answer 24

Constant Waves

Question 25

What are the characteristics of a Pacer Rhythm?

Answer 25

Pacer spike at the P wave

Question 26

What are the characteristics of Ventricular Standstill?

Answer 26

Only P waves

Question 27

What is asystole?

Answer 27

Flat line

Question 28

Answer 28

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

Question 29

What is a First Degree A-V Block?

Answer 29

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

Question 30

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

Answer 30

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

Question 31

What is a Mobitz II Second Degree Block?

Answer 31

P-P are equal P-R's are equal Multiple dropped
