(A). MKK4cko-TAC mice are more susceptible to ventricular arrhythmias and slowed conduction velocity. (B). Most activation maps from MKK4F/F hearts showed a sequential activation pattern, beginning with a localized activation of one region ...

(A). Layout of 64 channel arrays. (B). The box shows the position of MEAs. (C). The mapping waveforms from a Langendorff perfused rabbit heart. The activation map shows the acceleration of conduction after application of ...
