1
Q

AF reduces CO by how what proportion due to the lack of proper ventricle priming by atria?

A

10-20%

2
Q

What is the definition of AF?

A

An irregularly irregular atrial rhythm at around 300bpm transmitted intermittently by the AVN

3
Q

First three things to do if acutely unwell/haemodynamically unstable

A

Give oxygen, take U+Es, emergency cardioversion (IV amiodarone if unavailable)

4
Q

Should treatment be postponed in order to administer anti coagulation?

A

No

5
Q

What else other than the first 3 steps and anti coagulation should be done?

A

Treat associated illness (eg pneumonia) and rate control

6
Q

What is first line drug therapy for ventricular rare control?

A

Vermapril or bisoprolol

7
Q

What is 2nd line treatment for ventricular rhythm control?

A

Digoxin or amiodarone

8
Q

What should you use for anti coagulation?

A

LMWH

9
Q

Why use LMWH?

A

Means that cardioversion can still be done

10
Q

How long is the period in which you can carry out cardioversion Fter onset?

A

48 hours (can do after if echo shows no thrombi)

11
Q

How is cardioversion carried out?

A

O2- ITU - sedation - shock (200,360,360J if monophasic) (200J if biphasic) or amiodarone

12
Q

What are the main goals for pe remnant AF treatment?

A

Rate control and anti coagulation

13
Q

When might rhythm control be more important?

A

If young, AF from corrected cause, symptomatic or presenting for 1st time with idiopathic “lone” AF
