Question 9

leads

Answer 9

on the right, smoke over fire
on the left, snow over grass
brown in the middle

Question 10

athletes have _____ resting HR

Answer 10

lower

heart muscles are stronger so they pump more blood with each beat

Question 11

bradycardia symptoms

Answer 11

lightheadedness
dizyness
chest pain
change in LOC
syncope

lack of oxygen to brain and low CO

Question 12

tachycardia causes

Answer 12

infection, IV drug use, anxiety, electrolytes, anemia, low blood volume

Question 13

bradycardia treatment

Answer 13

atropine (increases HR)

transcutaneous pacing

Question 14

tachycardia treatment

Answer 14

adenosine (slows HR) 6mg-12mg

cardioversion

vagal maneuver (bear down, blow through syringe)

Question 15

premature atrial contractions look like

Answer 15

an extra beat here and there, normal spacing then two in a row then normal spacing again

Question 16

premature ventricle contractions look like

Answer 16

inversion of T or QRS waves, wonky beats

Question 17

premature contractions (A and V) can be caused by

Answer 17

caffine, alcohol, stress

Question 18

premature contractions possible symptoms

Answer 18

fluttering, chest pain, diapheretic, lightheaded, dizzy

Question 19

Acute Coronary Syndrome (ACS)

Answer 19

any condition with sudden reduction or blockage to heart

usually see ST changes

Question 20

ST elevation

Answer 20

STEMI
ST Elevated Miocardial Infarction
a heart attack, complete blockage

Question 21

ST not elevated but weird or inverted

Answer 21

NSTEMI
Non ST Elevated Miocardial Infarction

Question 22

why get a 12 lead for an MI instead of the 5 lead in telemonitoring?

Answer 22

a 12 lead will show where in the heart the infarction is happening, gives a better picture, different interventions for different types of infarction

Question 23

s/s MI

Answer 23

chest pain, radiating down left arm (in males)
women may experience back pain, GI issues or tireness

Question 24

ischemia is

Answer 24

reduced blood flow

causes the chest pain

Question 25

morphine decreases ____ nitro decreases _____

Answer 25

morphine decreases heart load work nitro decreases pain

Question 26

nitro contraindicated meds

Answer 26

Erectile Dysfunction or vasodilator meds

Question 27

heparin is an

Answer 27

anticoagulant

Question 28

Heart blocks: if R is far from P it must be

Answer 28

1st degree PR > 20 seconds all p waves conduct

Question 29

Heart blocks: if PR gets longer than a QRS drop it must be

Answer 29

type 1 Wenckebach (second degree) progressive prolongation of PR interval until QRS dropped

Question 30

Heart blocks: if PR stays normal and QRS quits it must be

Answer 30

type 2 Mobitz (second degree) constant PR interval probably needs a pacemaker

Question 31

Heart blocks: if P and QRS beat independently it must be

Answer 31

a complete 3rd degree complete disruption of AV conduction needs immediate intervention, probably ablation

Question 32

3 types of atrial dysrhythmias

Answer 32

supraventricular tachycardia (SVT) atrial fibrilation (AFib) atrial flutter SUPER AA

Question 33

SVT (supraventricular tachycardia) decreases

Answer 33

CO

Question 34

SVT (supraventricular tachycardia) treatment

Answer 34

electrical synchronized cardioversion

Question 35

synchronized cardioversion

Answer 35

blocks off AV node less jules than defib for patients that still have a pulse synchronized for the R waves

Question 36

AFib has atrias

Answer 36

quivering very fast, not pumping as they should

Question 37

AFib causes decreased

Answer 37

CO

Question 38

AFib can cause ______ blood, increasing blood clot potential

Answer 38

pooling

Question 39

AFib med treatment is

Answer 39

anticoagulants (heparin)

Question 40

ablation destroys

Answer 40

the tissue causing the irregular rhythm

AFlutter has a _____ pattern

Answer 41

sawtooth, and no equal spacing between QRSs

Question 42

ventricular tachycardia Torsade de Pointes VTach

Answer 42

tombstones/fireman hats treatment differs based on whether or not patient has a pulse CHECK PULSE BEFORE ANY INTERVENTION
