Life-threatening features

If a patient presenting with an atrial tachycardia has been adequately resuscitated medical and has ongoing evidence of haemodynamic compromise, syncope, myocardial ischaemia or severe heart failure then proceed as below:

1. Deliver up to 3 synchronised DC shocks (sedate patient if conscious)
2. If unsuccessful – give amiodarone 300mg over 10-20 minutes
3. Reattempt synchronised DC cardioversion
