Figure 2. Cellular alternans in CaTs.

Figure 2

(A) Examples of signals at progressively greater frequencies without and with alternans recorded, with results from 1 cell in each group shown in a column. (B) Threshold for cellular CaT alternans for each condition. Each point represents the result from a single cell. Horizontal lines show medians and interquartile range. n/N = 15 cells from 5 dogs per group for all measures. Nonparametric Kruskal-test. n/N, cells/dogs per group; CTL, control; AF, atrial fibrillation atrial cells; AF + DTL, dantrolene-treated AF cells; CTL + Caff, caffeine-treated CTL atrial cells.
