Q

cardiac conduction

A

1) sa node (initiates rate)
2) av node
3) bundles of His
4) purkinjie fibers

18
Q

describe dubins method

A

300, 150, 100, 75, 60, 50, 43, 38, 33, 30

19
Q

_______ of chambers provokes their contraction

A

depolarization

20
Q

this is the resting between beats

straight line on paper

A

isoelectric line

21
Q

ability to contract

A

automaticity

22
Q

describe atrial flutter

A

saw tooth

atrial rate about 250-350

23
Q

describe atrial fib

A
  • no p waves
  • always irregular
  • *most common dysrthythmia d/t CHF
24
Q

treatment of atrial fib

A
  • cardizem (CCB)
  • digoxin (glycoside)
  • amiodarone
  • cardioversion
  • anticoagulant
25
describe sinus tachy
- rate > 150 | treatment: beta blocker and calcium channel blocker
26
examples of beta blockers
metoprolol or labetolol
27
examples of calcium channel blockers
ditiazen (cardizem)
28
describe atrial tachy
- rate >150 | - p wave is irregular but visible
29
treatment of atrial tachy
- adenosine (adenocard) - diltazem (cardizem - carotid massage - cardioversion
30
describe PVCs
-no p wave preceeding PVC -poor perfusion BAD: frequency, couplets, multiple foci
31
describe SVT
- QRS is narrow - rate is >160 or 200 - cannot determine p wave (not visible) - treatment is adenosine or cardioversion
32
what to do in a code if no pulse
1) compression 2) epi 3) defibrilaltion
33
describe v fib
no contraction no C.O. treatment is defibrillation
34
describe v tach
no p wave rate is about 150 go in and out of it
35
treatment of v tach if no pulse
compression
36
treatment of v tach if pulse
amiodarone
37
list of meds for v tach
``` shock/cardioversion epi vasopressin amiodarone lidocaine mg sulfate ```
38
describe polymorphic
v tach in multiple areas d/t lack of mg give IV mg
39
always check what first
pulse THEN start compressions if NO pulse
40
if pt talks to you while in v tach...
check BP ask about chest pain or SOB **about to code, give O2
41
if HR increases
BP decreases (inverse)
