Front 1

Cardiac output at rest is

Back 1

4-5L

Front 2

Rate estimation order

Back 2

300,150,100,75,60,50

Front 3

The distance between the heavy black lines represents

Back 3

1/300 min, inverse for rate

Front 4

Rhythm strips are how long

Back 4

12 seconds

Front 5

3 choices from irregularly irregular rhythm

Back 5

Atrial fib(atrial rate greater than 360 and many different ps), wandering atrial pacemaker (less than 100 rate in COPD), and multimodal atrial tachy (WAP greater than 100 in COPD)

Front 6

Why are rhythm strips done in lead two?

Back 6

Sinus p waves are always upright in lead two and v 5

Front 7

If a p wave is present before every qrs than the origin of the rhythm is usually

Back 7

Supraventricular

Front 8

If the number of p waves are greater than the number of qrs complexes than what is present?

Back 8

Heart block

Front 9

MAT and WAP have at least how many atrial pace makers

Back 9

3

Front 10

Wandering pacemaker

Back 10

Irregular rhythm produced by the pacemaker activity wandering from the SA node to nearby atrial foci. Produces cycle length variation as well as variation in shape in p wave however rate is normal

Front 11

Wide qrs implies

Back 11

Cell to cell transmission instead of conduction pathway

Front 12

Premature atrial contractions occur when

Back 12

Sooner than expected

Front 13

Paroxysmal supraventricular tachy

Back 13

150-250, p waves in front of every qrs and qrs is narrow

Front 14

Atrial flutter

Back 14

250-350, saw tooth appearance, av block usually 2 to 1 so vent rate is 150, next common is 4 to 1 with vent 100 and 3 to 1 with vent rate of 75

Front 15

Atrial fibrillation

Back 15

350-450, many irritable foci, p waves are all different looking,

Front 16

A fib plus bradycardia is a sign of

Back 16

Digitalis toxicity or diseased av node

Front 17

PVC vs escape beat

Back 17

Vent escape has long pause then ventricles take over, PVC happens before the sinus p wave has a chance

Front 18

Bigeminty vs trigeminy

Back 18

Bi- PVC in between every normal beat, tri- two normal than one PVC

Front 19

Ventricular couplet

Back 19

Two PVCs in a row

Front 20

PVC

Back 20

Wide qrs of just one wave, compensatory pause after, increased filling and a larger stroke volume in the beat post premature contraction

Front 21

Premature atrial contraction do not have

Back 21

A compensatory pause

Front 22

Things that cause a ventricular focus to be irritable

Back 22

Low o2 and k

Front 23

Long qt has a risk for

Back 23

V tach

Front 24

V tach

Back 24

Wide qrs at rate of 100-250, chest pain, chf, syncope

Front 25

When may a dangerous arrhythmia result

Back 25

When a PVC falls on a t wave

Front 26

Paroxysmal v tach

Back 26

150 to 250

Front 27

V tach signs

Back 27

Tachy of 100-200 with 3 or more beats, wide qrs at .16, av dissociation, unidirectional in leads v1 to v6, brugada and josephson signs

Front 28

Josephson sign

Back 28

Notching if the S wave

Front 29

Brugada sign

Back 29

Greater than .1 sec from r to bottom of s wave

Front 30

V fib has

Back 30

No beats at all, flutter does

Front 31

Torsad us when

Back 31

The r wave is prominent in the v tach but then the S wave seem prominent , undulating sinusoidal appearance

Front 32

Rate of v fib

Back 32

Vent rate if 350-450

Front 33

First degree av block

Back 33

Pr longer than .2

Front 34

Mobitz one

Back 34

Wenckebach block, inferior wall mi which affects the av node, progressive lengthening of pr interval until v beat dropped

Front 35

Mobitz two

Back 35

Block occurs below av node, sudden drop of expected v beat after normal p wave

Front 36

Third degree heart block

Back 36

Sinus and ventricular beats are unrelated, 20-40 beats per min, a systole may be next
