Experimental quasi-periodic on-off switch of EADs. A. APD series (left) measured in a rabbit ventricular myocyte. Quasi-periodic slow transitions of APD between EAD (red shading) and no EAD states (grey shading) are apparent, where a, b and c denote transitions between these two phases. Random jumps in APD also occur amidst these phases. APs with EADs (black/red arrows) and without EADs (gray arrow) are shown. B. AP trains right straddling phase transition points. Only occasional beats (*) interrupt the EAD (red bars) or no EAD phases (gray bars). PCL = 3s.
