Interval fields for the selected rhythm will be added here.

Differential diagnosis

AVNRT

AV nodal reentrant tachycardia

Short VA interval and concentric retrograde activation.

Leading
72%
ORT

Orthodromic reciprocating tachycardia

Accessory pathway participation has not been excluded.

Possible
48%
AT

Atrial tachycardia

Current findings favor an AV node-dependent mechanism.

Less likely
21%
JT

Junctional tachycardia

Current observations argue against an automatic junctional rhythm.

Excluded
4%

Pacing maneuvers

01
Ventricular pacing

His-refractory PVC

Assess whether a ventricular stimulus advances, delays, or terminates the tachycardia.

Why this maneuver?

This is currently the highest-yield step for separating AVNRT from an accessory pathway-mediated tachycardia.

Alternative maneuvers

Current interpretation

Evidence and reasoning

Current synthesis

Typical AVNRT is favored, but ORT remains unresolved.

The short septal VA interval and concentric retrograde activation support AVNRT. A ventricular maneuver is still required before excluding a concealed septal accessory pathway.

Short septal VA

Compatible with typical AVNRT.

Concentric atrial activation

Earliest atrial activation is septal.

Accessory pathway unresolved

No pathway-specific ventricular maneuver is recorded.

Clinical review required

Recommendations are decision-support outputs and require review against the complete study context.
