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]]. | |||
