'''The QRS duration indicates how fast the ventricles depolarize. The normal QRS is < 0.10 seconds'''  


The ventricles depolarize  normally within 0.10 seconds. When this is longer than 0.12 seconds, this is a [[conduction delay| conduction delay]]. Possible causes of a QRS duration > 0.12 seconds include:
