Wide complex (QRS>0.12)
Ventricular tachycardia regular (mostly) 60-100 bpm 110-250 bpm ventricle (VT) AV-dissociation no rate reduction (sometimes accelerates)
ventriclefibrilleren irregular 60-100 bpm 400-600 bpm ventricle (VT) AV-dissociation none
Ventricular flutter regular 60-100 bpm 150-300 bpm ventricle (VT) AV-dissociation none
AIVR regular (mostly) 60-100 bpm 50-110 bpm ventricle (VT) AV-dissociation no rate reduction (sometimes accelerates)
Torsade de pointes regular 150-300 bpm ventricle (VT) AV-dissociation no rate reduction (sometimes accelerates)
Supraventricular tachycardia with block (ir)regular depending on SVT 150-250 bpm 75-200 bpm atria (SVT) absent temporary increased AV-block (eg 4:1)
