Secondly it is important to assess the origin of the arrhythmia:
*If the QRS < 120ms (i.e. a narrow complex), then it is either a [[Sinus node rhythms and arrhythmias|sinus arrhythmia]], [[Supraventricular Rhythms|supraventricular rhythm]] or a [[Junctional Tachycardias|junctional tachycardia]]. In tachycardias, this [[Media:narrow_tachycardia_flow.png|flowchart]] will lead to the right diagnosis.

*If the QRS > 120ms it is either a [[Ventricular Arrhythmias|ventricular tachycardia]] or a [[Supraventricular Rhythms|supraventricular rhythm]] with additional [[Intraventricular Conduction|bundle branch block]]. This is a challenging difficulty in arrhythmia diagnosis, therefore a [[media:wideQRS_tachycardia_flow.png|flowchart]] has been developed for this.<cite>brugada</cite>
