View source for AV nodal reentry tachycardia

'''AV nodal reentry tachycardia''' (AVNRT) is caused by the presence of an additional electrical pathway in the AV node, which forms a reentry circuit in the AV node. On the ECG there are fast, narrow, regular QRS complexes without normal P-waves. In some leads, small P-waves may be visible at the end of the QRS complex (retrograde P).

AVNRT can often be terminated by [[vagal manoeuvres]] or [[adenosine]]. Some patients can be managed by only performing vagal manoeuvres when they feel the AVNRT. Others require [[Antiarrhythmic drugs|antiarrhythmic treatment]] with [[beta blockers]], [[verapamil]], or [[flecainide]].
