atrioventricular nodal reentrant tachycardia

AVNRT Cardiology The most common form of paroxysmal SVT Treatment Antiarrhythmics are rarely successful; catheter ablation of the fast P wave causes complete heart block in 10%, requiring pacemaker placement; selective catheter ablation of the atrial end of the slow PW using radiofrequency current may eliminate AVNRT with little risk of AV block. See Supraventricular tachycardia.

atrioventricular nodal reentrant tachycardia

Abbreviation: AVNRT
The most common supraventricular tachycardia, resulting from abnormal conduction of electrical impulses through a self-sustaining circuit in the atrioventricular node. It occurs more often in women than in men, often in their twenties. The heart rate is usually between 150 and 250 bpm.
Synonym: junctional reciprocating tachycardia See: re-entry
