Q

Maintenance Treatment for AF

A 
First line rate control = Monotherapy 
-	Beta Blocker (not Sotalol) 
-	Rate limiting CCB 
-	Verapamil 
Second line rate control = Dual therapy 
-	Beta blocker 
-	Diltiazem – Cardioselectivie CCB 
-	Digoxin 
Third line 
-	Rhythm control 
o	Beta blocker – Sotalol 
o	Oral arrhythmic drug

Q

When do you consider stroke prevention in patients with Afib or Atrial flutter
(2)

Q

Types of Ventricular Tachycardia (4)

A
  • Pulseless of AF
  • Unstable sustained ventricular tachycardia
  • Stable sustained ventricular tachycardia
  • Non - sustained ventricular tachycardia

Q

What do you do in each of these options

  • Pulseless of AF
  • Unstable sustained ventricular tachycardia
  • Stable sustained ventricular tachycardia
  • Non - sustained ventricular tachycardia
A

Pulseless AF = defib + CPR + Amiodarone

Unstable sustained ventricular tachycardia = directed current cardioversion

Stable sustained ventricular tachycardia
= IV anti-arrhythmic drugs

Non - sustained ventricular tachycardia = Beta Blocker

20
Q

Interaction with Amiodarone

A

enzyme inhibitor’

  • Grapefruits
  • Warfarin / Phenytoin / Digoxin
  • Statins (increase risk of myopthay)
  • QT prolongation drugs
21

- In atrial flutter / non paroxysmal AF in sedentary patients

  • Worsening of severe heart failure in sinus
A

Long half life
AF = 125-250mcg

Heart failure = 62.5-125mcg
