Cellular Distribution and MFB Alignment Does Not Correlate With VT Inducibility

(A) The spatial distribution of CM, MFB, FB, and blood vessels in zones 2 and 3 in iVT hearts and zone 3 in non-VT hearts was calculated (Online Figure 3). iVT (n = 5) and non-VT hearts (n = 4) and data are from the following number of sections: zone 2 iVT (29), zone 3 iVT (27), and zone 3 nonVT (23). *p < 0.05. (B) Conduits of directionally oriented MFB (arrow) in representative sections of zone 2 (iVT) and zone 3 (iVT and non-VT). (C) Relative axial alignment of MFB. Number of experiments is given in (A). ECM = extracelluar matrix; other abbreviations as in Figure 2.
