Q

Difference between synchronised and unsynchronised shocks?

A

synchronised shocks - timed with the ECG pattern - should give in any rhythm where a patient is conscious, basically tachycardias originating in the atria and in VT with a pulse

unsynchronised shocks are not timed with the ECG pattern - give this in rhythm where patient is unconsciousness - pulseless VT and VF

Q

Acute AF management?

  1. beta blocker
  2. digoxin
  3. amiodarone
