PS and PDL properties observed via optical mapping experiments from n = 6 rabbit hearts using two cameras, such that the entire epicardial wall is imaged.

Here, PSs were computed using the integral method using the “2 × 2+4 × 4” ring of points (Kuklik et al., 2017). Phase was computed for both PSs and PDLs with V(t) the normalized optical intensity and R(t) its Hilbert transform.
