Figure 4

Fold differences in ion channel transcripts. A: Same results as in Figure 3 expressed as the ratio of LA to RA mRNA levels. B: Comparison of LA ion channel mRNA levels from 31 patients in normal sinus rhythm relative to 12 patients who developed post-operative AF. Error bars are omitted in both panels due to transformation of the data and the subsequent loss of meaning. Data were transformed from cT values to equivalent fold differences, e.g., Fold Difference (mean CtLA − mean CtRA) = 2(mean CtLA − mean CtRA)17.
