Ventricular arrhythmias are almost allways wide-QRS-complex arrhythmias. When confronted with a wide-QRS-complex tachycardia it can be difficult to differentiate between a [[supraventricular tachycardia]] with [[aberrancy]] or [[Ventricular Tachycardia|ventricular tachycardia]]. A separate chapter deals with this dilemma: [[Approach to the Wide Complex Tachycardia]].

Ventricular arrhythmias are almost allways wide-QRS-complex arrhythmias. When confronted with a wide-QRS-complex tachycardia it can be difficult to differentiate between a supraventricular tachycardia with aberrancy or ventricular tachycardia. A separate chapter deals with this dilemma: Approach to the Wide Complex Tachycardia.

An overview of ventricular tachycardias, follow the Approach to the Wide Complex Tachycardia
example regularity atrial frequency ventricular frequency origin (SVT/VT) p-wave effect of adenosine
Wide complex (QRS>0.12)
Ventricular Tachycardia Vt small.svg regular (mostly) 60-100 bpm 110-250 bpm ventricle (VT) AV-dissociation no rate reduction (sometimes accelerates)
Ventricular Fibrillation Vf small.svg irregular 60-100 bpm 400-600 bpm ventricle (VT) AV-dissociation none
Ventricular Flutter Vflutt small.svg regular 60-100 bpm 150-300 bpm ventricle (VT) AV-dissociation none
Accelerated Idioventricular Rhythm Aivr small.svg regular (mostly) 60-100 bpm 50-110 bpm ventricle (VT) AV-dissociation no rate reduction (sometimes accelerates)
Torsade de Pointes Tdp small.svg regular 150-300 bpm ventricle (VT) AV-dissociation no rate reduction (sometimes accelerates)
Bundle-branch re-entrant tachycardia* Bb reentry small.svg regular 60-100 bpm 150-300 bpm ventricles (VT) AV-dissociation no rate reduction
