However, it is unclear how the right atrial (RA) posterior wall (PW) participates in AFLT circuit.

Multipolar catheters were deployed in RA and coronary sinus. RA shell was created during AFLT. Entrainment was performed to confirm CTI dependence and assess participation of various RA regions (septum\u2010Sep, PW, lateral wall\u2010LW). Data were analyzed for (1) RA activation patterns and (2) conduction time (CT) through various RA regions.<\/jats:p><jats:p> <jats:bold>\n            <jats:italic>Results:<\/jats:italic>\n          <\/jats:bold> Mean pt age was 70 \u00b1 13 years (all males; CCW = 10; CW = 5). Mean AFLT cycle length was 255 \u00b1 15 ms. Single activation wave front traversing sequentially CTI, Sep, and LW was seen in all pts and in 12 (80%; 9 CCW, 3 CW) this also traversed PW. Entrainment confirmed PW participation in 7 of these. Mean CT (in ms) through various RA regions was as follows: CTI = 69 \u00b1 27, Sep = 50 \u00b1 39, PW = 65 \u00b1 35, and LW = 76 \u00b1 35; P = NS.<\/jats:p><jats:p> <jats:bold>\n
