During wide complex tachycardia (heart rate > 100/min, QRS > 0.12 sec) the differentiation between supraventricular and ventricular origin of the arrhythmia is important to guide therapy. Several algorhythms have been developed to aid in this differentiation.

The ACC algorhythm [1]

SVT vs VT algorhytm. Adapted from [1]


Brugada criteria

Brugada criteria ter differentiatie van supraventriculaire ritmestoornissen (SVT's) van ventriculaire ritmestoornissen (VT's)[2]
Zijn er fusie of capture beats? (dit item komt niet uit de Brugada criteria, maar is wel heel specifiek) Ja? => VT specificiteit=100%
Fusionbeat.png
RS complexen afwezig over de voorwand? Ja? => VT sensitiviteit=21% specifiteit=100%
RS-interval in één van de precordiale afleidingen > 100 msec (bij patient zonder anti-arritmetica)? Ja? => VT sensitiviteit=66% specifiteit=98%
Is er AV-dissociatie? Ja? => waarschijnlijk VT (NB AV nodale re-entry kan ook AV-dissociatie geven!) sensitiviteit=82% specifiteit=98%
Morfologische criteria (als bovenstaande criteria geen uitkomst bieden)
LBTB patroon
Initiële R breder dan 40ms? Ja => VT
Rhythm RSratio.png
Slurred of notched neergaand been van S golf in afleiding V1 of V2 Ja => VT
Begin Q tot nadir QS >60 ms in V1 of V2? Ja => VT LR >50:1
Q of QS in V6? Ja => VT LR >50:1
RBTB patroon
Monofasische R of qR in V1? Ja => VT
R hoger dan R' (rabbit-ear sign)? Ja => VT LR >50:1
rS in V6? Ja => VT LR >50:1
