Figure 4. Study of arrhythmia in ring-shaped cardiac tissues.

(A) Poincaré plot for tissues at D14. n=24 tissues from three differentiations. (B) Tissue with FluoVolt dye in its relaxed/hyperpolarized state and contracted/depolarized state. (C) Representative plot of contraction strain (black) and fluorescence signal (green) of a tissue derived from video analysis of the FluoVolt dye.

Figure 4—video 1. FluoVolt live imaging of a ring at D15.
