SVT
adult algo
- vagal manoeuvre
- adenosine 6mg, then if unsuccessful:
- adenosine 12mg, then if unsuccessful:
- adenosine 18mg
- if still ineffective, verapamil/beta blockade, then if unsuccessful:
- synchronous DCCV 70-120J biphasic
paeds algo (APLS)
- vagal manoeuvre
- vascular access possible?
- adenosine 100 mcg/kg, wait 2 mins, then if unsuccessful:
- adenosine 200mcg/kg, wait 2 mins, then if unsuccessful:
- adenosine 300mcg/kg
- synchronous DCCV 1J/kg → 2J/kg if unsuccessful
SVT vs VT with aberrancy
- AV dissociation (P and QRS complexes) → VT
- can you find an old ECG?
right patient for VT:
- age >35
- structural or ischaemic heart disease
- Brugada, HOCM, see Sudden cardiac death
