Exam 2: Dysrhythmias Flashcards
1
Q
Sinus Brady
A
- Sinus node creates an impulse at a slower than normal rate
- < 60 bpm
2
Q
Sinus Brady Symptomatic Treatment
A
- Atropine ONlY if Symptomatic showing low perfusion ( Pale, cool & clammy )
3
Q
Sinus Tachy
A
- Faster than normal rate
- > 100
- Identify cause, slow HR
4
Q
Atrial Fibrillation
A
- Atria are “ quivering “
- No clear p waves, no atrial contractions, loss of atrial kick and irregular ventricle response
- Risk for excessive clotting ( DVT, PE )
- Higher risk for pts w hx of HTN, CHF, Obesity or CAD
5
Q
Atrial Fibrillation Treatment
A
- Stable: Beta blockers, CCB, Anticoagulant therapy, oxygen
- Unstable: Oxygen, cardioversion
6
Q
Atrial Flutter
A
- Can be a regular rhythm
- AFib is always irregular!
7
Q
Cardioversion
A
- Priority intervention when the client is awake and responsive.
8
Q
Defibrillation
A
- Emergency
- V Fib / V- Tach
- Client unconsious
9
Q
Shockable Rhythms
A
- Pulseless V Tach
- V Fib
Treat: Defibrillate
Continue CPR while getting it ready ^
10
Q
Nonshockable Rhythms
A
- Asystole
- PEA
Treat: CPR, Epinephrine
11
Q
Pulseless V Tach
A
- Over 100 bpm
- Can be with/ without pulse only shock pulseless v tach
12
Q
V Fib
A
- Ventricles don’t perform an effective heart beat
- Can happen - After heart attack
- Leading cause of sudden cardiac death
13
Q
Asystole
A
- Heart electrical system shut down no heartbeat
- CPR immediately!
14
Q
PEA
A
- Shows electrical activity but no palpable pulses due to electrical activity being too weak
- CPR immediately!
15
Q
Ventricular Tachy
A
- Tombstone pattern
S/S: Hypotension, palpitation, lightheadedness, ischemia ( chest pain ), anxiety
16
Q
PEA & Asystole Treatment
A
- Treatment the same
1. CPR
2. Epi
3. Figure out cause
