Types of wave splits. Splits of waves are observed when two waves collide, a propagating wave meets heterogeneous refractoriness, or during decremental conduction. Neighboring pixels show different action potential amplitudes and recoveries in different types of wave splits. A: Wave collisions. The action potentials show full amplitude in all the neighboring pixels. B: Decremental conduction. All the neighboring pixels show very small depolarizations. C: Heterogeneous repolarization. In this case, recovery from the previous depolarization is different in the neighbors, causing various amplitudes of action potentials.
