Overview
Sinoatrial nodal reentry tachycardia (SANRT) is caused by a reentry circuit localized to the SA node.
Causes
Life Threatening Causes
Life-threatening causes include conditions which may result in death or permanent disability within 24 hours if left untreated.

Causes in Alphabetical Order
Diagnosis
Electrocardiogram
- SA node reentry tachycardia has a normal activation sequence with normal appearing p-wave that precedes a regular, narrow QRS complex.
- Although it cannot be distinguished on the surface 12 lead EKG from sinus tachycardia, unlike sinus tachycardia, SA node reentry tachycardia does often terminate with vagal maneuvers.
