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
