Figure 6. Direction of zebrafish cardiac vector and its shift during heart regeneration.

Figure 6

ECG recorded from chest (A) and dorsal side (B) showing the direction of normal depolarization vector. (C) Shift in cardiac vector after ventricular injury. (D) Negative-directed R wave occasionally recorded by Probe 2. (E) Ratio of two-probe amplitude representing recovery of cardiac vector along with the regenerative process. Values are presented as the mean + SD. (F) Correlation coefficient between QT and RR interval of sham control, amputation and cryoinjury group.
