Fig. 3.
Chimeric Cx43 KO mice display many different premature ventricular complex (PVC) morphologies. In contrast to the controls, each chimeric mouse showed many different PVC morphologies. Representative examples of PVCs from different days in the same control and chimeric mice are shown, demonstrating a consistent PVC morphology in the control over 6 days of monitoring and several different PVC morphologies in the chimera over the same time span.
