An overview of ventricular tachycardias

	regularity	atrial frequency	ventricular frequency	origin (SVT/VT)	p-wave	effect of adenosine
Wide complex (QRS>0.12)
Ventricular Tachycardia	regular (mostly)	60-100 bpm	110-250 bpm	ventricle (VT)	AV-dissociation	no rate reduction (sometimes accelerates)
Ventricular Fibrillation	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)
