Lesson 6

Question 1

what’s longer sinus arrest/pause

Answer 1

arrest

Question 2

AV node is the one that

Answer 2

pauses

Question 3

any change in PR interval means..

Answer 3

stimulus from AV/junctional

Question 4

nodal his

Answer 4

pacemaker cells of AV node

lower region of the AV node

Question 5

retrograde p waves

Answer 5

going away from electrode

Question 6

premature junctional contractions

Answer 6

occur before normal rhythm and P waves are absent

Question 7

if PJCs have a P wave what are the called?

Answer 7

PAC!

Question 8

T/F a rhythm with a PJC is still sinus is they are few and far between

Answer 8

T! look at the whole picture

Question 9

junctional escape beat

Answer 9

retro P wave before R wave

prolong delay after junctional beat

normal beat long pause then the irregular one if its flipped and weird one is first its a PJC

Question 10

if a JER is over 60 its referred as a(n)…

Answer 10

accelerated JER

Question 11

first degree heart block

Answer 11

PR interval is greater then normal everything is the same

delayed through AV node

Question 12

seconds degree heart block type 1

Answer 12

P wave walking around doing its thing not giving a fuck

eventually ends up in refractory period and isn’t conducted

Question 13

second degree heart block type 2

Answer 13

dropped ventricular beats have a pattern

Question 14

sinus block vs heart block type 2

Answer 14

heart block is more frequent and persistent

Question 15

third degree heart block

Answer 15

lots of p waves very few QRS

Question 16

pressure to offload/onload

Answer 16

100mmHg

Question 17

RHF symptoms

Answer 17

pitting edema

Question 18

AV node regions

Answer 18

atrial nodal
nodal
nodal his

Question 19

PJC contraction

Answer 19

excited cell starts depolarization before SA node

Question 20

couplet

Answer 20

PJC pair

Question 21

burst

Answer 21

3+ PJCs in a row

Question 22

PJC rhythm

Answer 22

regular no P waves

Question 23

door bell rings gets up right away

Answer 23

NSR

Question 24

door bell rings takes awhile to get there

Answer 24

first degree heart failure

Question 25

door bell rings takes longer and longer to get there

Answer 25

second degree type 1

Question 26

door bell rings answers quick then gets group and doesn't go to rested

Answer 26

second degree type 2

Question 27

door bell rings doesn't give a fuck checks doors now and then but can't hear the fucking bell

Answer 27

third degree

Question 28

RSHF

Answer 28

decrease r side output

Question 29

RSHF clinical features

Answer 29

JVD | pitting edema

Question 30

___ sided HF can lead to ___ sided HF

Answer 30

right | left

Question 31

where does blood back up in RSHF

Answer 31

systemic/hepatic vasculature pushes to the lungs/left side

Question 32

Cardiogenic pulmonary edema prehospital care

Answer 32

``` ABC IV 12/15 lead maintain systolic 100mg via fluids non hypotensive CPAP, narcotics ```

Question 33

RSHF causes

Answer 33

sleep apnea | lung disease

Question 34

T/F pulmonary disease can increase pulmonary circulatory pressure

Answer 34

T!

Question 35

what does the increased pulmonary pressure cause ?

Answer 35

it causes the right ventricle to increase in size and fail also known as cor pulmonale

Question 36

LSHF

Answer 36

chronic hypertension causes left ventricle hypertrophy causes l ventricle to expand and fail decreases left side output
