Intermittent orthodromic capture of the earliest activation site during atrial pacing in a case with reentrant atrial tachycardia originating from the atrioventricular node vicinity

Constant pacing (S1–S1: 520 ms) from the right atrial appendage (RAA) during reentrant atrial tachycardia originating from the atrioventricular node vicinity. RA‐FW 1–2 was constantly captured antidromically. However, the earliest atrial activation site (EAAS = His1‐2) was orthodromically (red circl...

description Constant pacing (S1–S1: 520 ms) from the right atrial appendage (RAA) during reentrant atrial tachycardia originating from the atrioventricular node vicinity. RA‐FW 1–2 was constantly captured antidromically. However, the earliest atrial activation site (EAAS = His1‐2) was orthodromically (red circle) and antidromically (blue square) captured at a ratio of 3:1. The electrogram morphology at the EAAS was different between orthodromically and antidromically electrograms captured during pacing. Moreover, the interval between the S1 and orthodromically captured electrogram was gradually prolonged.[Image: see text]
