PST1 sites were identified on the epicardial model that was specific to that VF recording. Because geometric models differed slightly from run to run, the PST1 sites from each VF episode were mapped onto the final recorded geometry of each heart (which we term the heart's common model). This was done by first scaling the models along the z-axis so that the apices were co-terminous and then projecting each PST1 site along its triangle's surface normal vector to the common model's surface.

Global VF dynamics indicated by the number of compound rotors vs. time. (A) The VF0 source is a rotor pair on the LV (heart 4; same episode as Figure 4 and Supplementary material online, Video 1). (B) The VF0 source is a repetitive breakthrough on the LV (heart 6; same episode as Supplementary material online, Video 2). (C) The VF0 source is a rotor pair on the RV (heart 9; same episode as Supplementary material online, Video 3). Time 0 corresponds to the end of the S2. The times of the PST1-inducing wavebreaks are indicated by arrows.
PST1 formation at the ARVI was predominant, but not universal (Table 1). In 5 of the 10 hearts, in all episodes, PST1s formed in the ARVI region in a manner similar to Figure 4. In three additional hearts, this pattern was observed in most episodes (2/3 or 3/4). In the remaining two hearts, it occurred in only one episode. 2ff7e9595c
