Figure 9. ARI alternans in atrial electrograms in vivo.

Figure 9

(A) Examples of signals at various BCLs without and with ARI alternans recorded, with results shown for a CTL dog (top) and an AF dog before (middle) and after DTL administration (bottom). (B) BCL threshold for ARI alternans under each condition. Each point represents the result from a single atrium. Horizontal lines show median and interquartile range. N = 5 for CTL and CTL + DTL; N = 9 for AF and AF + DTL. Nonparametric Kruskal-Wallis test.
