TCW incidence is greater with increasing rate and in HF while velocity is unchanged. (A) Incidence of TCWs in NAMs (52 myocytes from four atria) and HFAMs (46 HFAMs from four atria). (B) Box-plot summary of rate dependence of TCW propagation velocities. Box boundary closest to zero indicates the 25th percentile, the line in the box marks the median, boundary of the box farthest from zero indicates the 75th percentile while error bars above and below the box indicate the 90th and 10th percentiles, respectively (×’s are outliers). (C) TCWs in a paced human NAM and (D) a pig NAM. *P < 0.05, **P < 0.01, ***P < 0.001 for NAMs or HFAMs within pacing rates, two-way RM ANOVA. †P < 0.05, ††P < 0.01, †††P < 0.001 between NAMs and HFAMs within pacing rates, two-way ANOVA.
