Hierarchical clustering. A, Two‐way hierarchical cluster analysis applied to 79 genes and to samples of right ring (n=4), retroaortic node (n=5), sinus node (n=5), atrioventricular node (n=4), atrial muscle (n=4), and ventricular muscle (n=4). B, Plot of ∆Ct values of all transcripts for ventricular muscle vs those for right ring and plot of ∆Ct values of all transcripts for retroaortic node vs those for right ring. Line represents y=x. C, Spearman rank order correlation data for same samples used for cluster analysis. AM indicates atrial muscle; AVN, atrioventricular node; RAN, retroaortic node; RR, right ring; SN, sinus node; VM, ventricular muscle.
