Atrial Flutter EKG description

Answer 10

• HR: A 250-350 bpm
• PR not measurable
• normal QRS
• P waves look sawtooth

Question 11

treatment of ventricular tachycardia

Answer 11

• with pulse= antiarrhythmics: procainamide, sotolol, amiodarone)
• torsades= IV magnesium
• stop meds that prolong QT
• No pulse= CPR

Question 12

treatment of sinus bradycardia

Answer 12

-treat underlying causes:
airway, O2 PRN
cardiac monitor
IV & ECG
-Symptomatic:
atropine (0.5mg Q3-5min.)
transcutaneous pacing
dopamine 2-20mcg/kg Qmin.
epinephrine 2-10mcg/min.

Question 13

treatment of 1st degree AV block

Answer 13

• treat underlying cause
• check medication
• monitor for progression
• requires no tx

Question 14

treatment of 2nd degree AV block type 1

Answer 14

• symptomatic:
  
  • atropine, dopamine, epinephrine to increase HR
• pacemaker
• asymptomatic:
  
  • monitor rhythm w/ trans. pacemaker

Question 15

treatment of 3rd degree AV block

Answer 15

• transcutaneous pacemaker
• perm. pacemaker
• increase HR: atropine, dopamine, epinephrine

Question 16

treatment of ventricular fibrillation

Answer 16

1) shock
2) CPR 2 min., IV/IO ass.
3) shock
4) CPR 2 min., epinephrine Q3-5min.
5) shock
6) CPR 2 min., amiodarone, treat reversible causes

Question 17

treatment of 2nd degree AV block type 2

Answer 17

1) treat underlying cause
2) if symptomatic:
- atropine 0.5mg max 3mg
- TP
- dopamine 2-20mcg/kg
- epinephrine 2-10mcg/min.
3) transveneous pacing
4) will need perm. pacemaker

Question 18

treatment of sinus tachycardia

Answer 18

• treat underlying cause
• Beta Blockers (metoprolol)
• Calcium Channel Blockers (diltiazem)
• vagal maneuvers

Question 19

treatment of PVC’s

Answer 19

• treat underlying cause
• check pulses
• drug therapy: Beta Blockers & amiodarone

Question 20

treatment of Atrial Flutter

Answer 20

1) control rate:
- digoxin
- Beta Blockers (metroprolol)
- Calcium Channel Blockers (dilitiazem)
2) convert to SR:
- amiodarone
- ibutilide
3) catheter ablation
