Atrioventricular Node Reentry Supraventricular Tachycardia Differential Diagnoses

  • Author: Glenn T Wetzel, MD, PhD; Chief Editor: Stuart Berger, MD  more...
Updated: May 30, 2014

Diagnostic Considerations

The permanent form of junctional reciprocating tachycardia (PJRT) is difficult to distinguish from atypical (fast-slow) atrioventricular node reentrant tachycardia (AVNRT).[11, 12]

Another rare mechanism is verapamil-sensitive atrial tachycardia originating from near the atrioventricular node.[13]

The patient's heart rate is approximately 146 beats per minute with a normal axis. Note the pseudo S waves in leads II, III, and aVF. Also note the pseudo R' waves in V1 and aVR. These deflections represent retrograde atrial activation.
