Flashcards in AF management-see chegg for more Deck (13):
AF reduces CO by how what proportion due to the lack of proper ventricle priming by atria?
What is the definition of AF?
An irregularly irregular atrial rhythm at around 300bpm transmitted intermittently by the AVN
First three things to do if acutely unwell/haemodynamically unstable
Give oxygen, take U+Es, emergency cardioversion (IV amiodarone if unavailable)
Should treatment be postponed in order to administer anti coagulation?
What else other than the first 3 steps and anti coagulation should be done?
Treat associated illness (eg pneumonia) and rate control
What is first line drug therapy for ventricular rare control?
Vermapril or bisoprolol
What is 2nd line treatment for ventricular rhythm control?
Digoxin or amiodarone
What should you use for anti coagulation?
Why use LMWH?
Means that cardioversion can still be done
How long is the period in which you can carry out cardioversion Fter onset?
48 hours (can do after if echo shows no thrombi)
How is cardioversion carried out?
O2- ITU - sedation - shock (200,360,360J if monophasic) (200J if biphasic) or amiodarone
What are the main goals for pe remnant AF treatment?
Rate control and anti coagulation
