Ventricular Arrhythmias: Difference between revisions

Revision as of 18:58, 24 February 2013

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
	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
