Overview
Sinoatrial node reentrant tachycardia (SANRT) is caused by a reentry circuit localised to the SA node,
Diagnosis
Electrocardiogram
- SA node reentry tachycardia results in a 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.
