Abstract

Tachycardia with narrow QRS complex have a QRS interval less than or equal to 120 ms, and a frequency greater than or equal to 100 bpm. 95% of the cases are supraventricular tachycardia, which originates from above the division of the bundle branches; 5% are ventricular tachycardia, particularly idiopathic ventricular tachycardia in children which can have a QRS interval less than 120 ms. Common types of narrow QRS complex tachycardia include atrioventricular nodal reentrant tachycardia (AVNRT), atrioventricular reentrant tachycardia (AVRT) and atrial tachycardia.
