Upper common pathway analysis using late atrial premature depolarization in atrioventricular nodal reentry tachycardia
Authors' conclusion
The LAPD maneuver revealed that the presence of UCP is indicated in only rare cases of AVNRT. In most AVNRT cases, the atrium is involved in the reentry circuit.
