Secondly it is important to assess the '''origin of the arrhythmia''':
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>

Normal heart rhythm is explained in:
*[[Sinus node rhythms and arrhythmias]]
Non-normal heart rhythms (arrhythmias) are described in:
*[[Supraventricular Rhythms]]
*[[Junctional Tachycardias]]
*[[Ventricular Arrhythmias]]
*[[AV Conduction]]
*[[Genetic Arrhythmias]]
*[[Pacemaker]]
*Flowchart: [[media:wideQRS_tachycardia_flow.png|Approach to the Wide Complex Tachycardia]]
*Flowchart: [[Media:narrow_tachycardia_flow.png|Approach to the Narrow Complex Tachycardia]] Adapted from <cite>ESCnarrowQRS</cite>.
