Figure 2. Average number of arrhythmias by phase.
Comparative graphs showing the average number of each arrhythmia type by phase for the control, lidocaine and riluzole groups. Note that riluzole and lidocaine significantly reduced the number of Phase 2 non-sustained and sustained arrhythmias. Note also that riluzole and lidocaine reduced the number of Phase 1b sustained arrhythmias but that this was not significant for lidocaine. In addition, riluzole significantly reduced the number of Phase 2 PVCs whereas lidocaine had minimal effect.
