K/Na/Cx43 NRVF rescued normal conduction velocity. A.

<p>Activation maps from monolayers of myocytes only (M, left), uninfected NRVF/NRVM co-culture (UI Fb/M, middle), and K/Na/Cx43 NRVF/NRVM co-culture (K/Na/Cx43 Fb/M, right). <b>B.</b> Quantification of conduction velocities at varies pacing cycle lengths in monolayers of myocytes (filled circles), UI Fb/M (open circle), and K/Na/Cx43 Fb/M (filled square).
