Flashcards in level 4 test 2 9.2 Deck (26):
1

stable SVT drugs

cannot distinguish P wave from the T wave
vagal stimulation, Adenosine, beta blockers, calcium channel blockers, amiodarone. If client becomes unstable cardiovert

2

Unstable svt

cardiovert

3

Sinus bradycardia

atropine (anticholinergic) Pacemaker may also be required

4

sINUS TACHYCARDIA

beta blocker can be given to reduce HR and decrease myocardial oxygen consumption

5

A fib

calcium channel blocker, beta blocker, digoxin, dronedarone(multaq)
Cardioversion may convert to NSR

6

first degree AV block

Prolonged AV conduction shows up as prolonged PR interval
No treatment

7

Premature ventricular contraction

is an contraction originating from an ectopic focus in ventricles. QRS is wide and distorted. if cuased by hypoxia administer O2. Drug therapy- beta blocker, procainamide, amiodarone, lidocaine

8

Ventricular fibrilation

Ventricle is quivering. TX cpr and ACLS with defib

9

Stable V tach

procainamide, sotalol, amiodarone, lidocaine

10

v tach with no pulse

CPR and defib followed by epinephrine and amiodarane

11

asytole

cpr, acls, epi and atropine, intubation and pacemaker

12

ischemia

ST segment depression and or t wave inversion

13

injury and infarction

worsening stages of ischemia cause st semgent elevation

14

P wave

atrial depolarization (contraction) 0.06-0.12

15

Pr interval

beginning of p wave to beginning of QRS complex represent impulse going through atria, av node and bundle of his. 0.12-0.20

16

QRS interval

depolarization (contraction)of both ventricles.less than 12

17

st segment

12

18

t wave

16

19

qt interval

34-43

20

afterload

peripheral resistance against which the left ventricle must pump

21

preload

the volume of blood in ventricles at the end of diastole, before next contraction

22

failure to capture

spike with asystole

23

Failure to pace

asystole with no spike

24

Failure to sense

a spike and nothing after it or in the wrong spot

25

NON stemi

no st elevation with raised troponin they had their heart hurt already so we cannot save tissue at this point. NOT an emergency but they need to be fixed. Give then Nitro and when they are stable take them to cath lab. MONA

26

Myocardial infarction

troponin high and st elevated
