Regular narrow complex Tachycardia Possibility to be SVT if rate more than 150 Stable : 1 Vagal manures 2 Adenosine 6 mg if not reverted 12 mg 3 Other rate limiting drugs /Amiodarone Refractory to drugs or unstable Cardioversion
Since this was narrow complex irregular tachy, so one of the differentials will be AF, So we should be sure of duration of it is >12 hours, may be we have to defer cardioversion or anticoagulate 1st or what Plz clear this confusion
