An overview of ventricular tachycardias, follow the wide complex tachycardia flowchart

	example	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
Accelerated Idioventricular Rhythm		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)
Bundle-branch re-entrant tachycardia*		regular	60-100 bpm	150-300 bpm	ventricles (VT)	AV-dissociation	no rate reduction
*) Bundle-branch re-entrant tachycardia is extremely rare
