1

Where is the P, QRS, andwave?

2

Using the rhythm below how would you calculate the heart rate?

Count the peaks (the R waves) and multiply times 10.

Example: 5 peaks X 10 = 50 beats per minute

3

What are the common signs and symptoms for most dysrhythmias?

Common signs and symptoms for dysrhythmias:

  • heart palpitations
  • short of breath
  • anxiety
  • dizziness
  • decreased level of consciousness

4
Identify this rhythm:

normal sinus rhythm

70 beats per minute

5
Identify this rhythm:

sinus bradycardia

50 beats per minute

6
Identify this rhythm:

sinus tachycardia

130 beats per minute

7
Identify this rhythm:

(immediate complication)

asystole

8
Identify this rhythm:

(immediate complication)

ventricular fibrillation

9
Identify this rhythm:

(immediate complication)

ventricular tachycardia

10
Identify this rhythm:

(immediate complication)

myocardial infarction

11
Identify this rhythm:

atrial fibrillation

12
Identify this rhythm:

atrial flutter

13
Identify this rhythm:

1st degree AV block

PR interval is elongated

 

14
Identify this rhythm:

2nd degree AV block Type 1 (Wenkebach/Mobitz I)

PR interval gets longer and longer and then it drops

15
Identify this rhythm:

2nd degree AV block Type 2 (Mobitz II)

PR interval stays the same and then QRS is missing

16

What is common about most heart blocks?

Heart blocks are:

  • typically less than 60 beats per minute
  • have an elongated PR interval
  • will receive atropine if showing symptoms
  • if atropine doesn't work, client will either get cardioversion or a pacemaker.

 

17
Identify this rhythm:

(Immediate complication)

3rd degree heart block (complete heart block)

18
Identify this rhythm:

(Immediate complication)

supraventricular tachycardia

19
Identify this rhythm:

(Immediate complication)

torsades de pointes

20
Identify this rhythm:

normal sinus rhythm with pre-ventricular contractions (PVC's)

21
Medications:

sinus tachycardia

  • give meds to decrease the heart rate:
    • ACE inhibitors
    • ARBs
    • Beta blockers
    • Calcium channel blockers
    • Digoxin

22
Interventions:

asystole

Immediate complication

Interventions for asystole:

  • start CPR
  • epinephrine
  • NO defibrillation

23
Interventions:

ventricular fibrillation

Immediate complication

Interventions for ventricular fibrillation:

  • "defib the V-fib"
  • CPR
  • epinephrine
  • amiodarone (or lidocaine)

24
Interventions:

ventricular tachycardia

(Immediate complication)

Interventions for ventricular tachycardia:

  • Pulseless V-tach
    • CPR
    • defibrillate
    • epinephrine
    • amiodarone (or lidocaine)
  • With a pulse
    • amiodarone (or lidocaine)

25
Medications:

atrial fibrillation and atrial flutter

  1. high risk for blood clots
    • antiplatelets
    • anticoagulants
  2. to decrease heart rate
    • beta blockers
    • calcium channel blockers
    • digoxin

26
Interventions:

myocardial infarction

Immediate complication

  1. give "OANM"
    • oxygen
    • aspirin
    • nitroglycerin
    • morphine
  2. "clot busters" if caused by a clot
    • T-PA
  3. cardiac catheterization if caused by plaque

 

27
Interventions:

supraventricular tachycardia

  • vagal maneuvers (carotid sinus massage, beardown/valsalva)
  • cardiovert with adenosine

28
Interventions:

normal sinus rhythm with pre-ventricular contractions

If getting 6 PVCs in a row or more than 6 in a minute treat with:

  • beta blockers
  • amiodarone
  • catheter ablation

29

What is a pacemaker?

A pacemaker uses batteries to send electric signals to the heart to help it pump correctly.

The pacemaker is connected to the heart by one or more wires.

 

30
Teaching:

Pacemakers

Teaching for pacemaker:

  • take pulse daily and report abnormalities
  • avoid contact sports
  • inform airport security about pacemaker (can set off security detector)
  • most electrical devices are OK to use: move back 5 - 10 feet if experience unusual feelings
  • use cell phone on opposite side of pacemaker site

 

31

What is defibrillation and cardioversion?

Defibrillation and cardioversion is giving the client a controlled electric shock in order to put the client back into a normal sinus rhythm. 

32

What is the difference between defibrillation and cardioversion?

  • Cardioversion is an administered shock synchronized with the QRS complex. 
  • Defibrillation is a randomly administered shock anytime during the cardiac cycle. It is always done in emergencies.

33

What is catheter ablation?

Catheter ablation is a procedure where a part of cardiac tissue is burned off to prevent dysrhythmias
