in afib Electrical cardioversion is synchronised
the R wave to prevent delivery of a shock during the vulnerable period of cardiac repolarisation when ventricular fibrillation can be induced
if the onset of the arrhythmia is less than 48 hours
offer rate or rhythm control
if the onset is more than 48 hours or is uncertain
start rate control
Following electrical cardioversion if AF is confirmed as being less than 48 hours the what is unnecessary ?
further anticoagulation is unnecessary
If the patient has been in AF for more than 48 hours then anticoagulation should be given for at least how many weeks prior to cardioversion
at least 3 weeks
alternative strategy is to perform a transoesophageal echo (TOE) to exclude a left atrial appendage (LAA) thrombus
If there is a high risk of cardioversion failure (e.g. Previous failure or AF recurrence after electrical ) then it is recommend to have at least
4 weeks amiodarone or sotalol prior to electrical cardioversion
Following electrical cardioversion patients should be anticoagulated for at least
4 weeks
