Sentence examples for scroll wave from inspiring English sources

Ionic inhomogeneities can also lead to an anchoring of the scroll wave; again fiber rotation works against this anchoring tendency.

Furthermore, the filament of the scroll wave can exhibit drift or meandering, transmural bending, twisting, and break-up.

A small fragment of the scroll wave, which we refer to as a seed wave, breaks off from a region near the core and eventually regenerates a scroll wave; this cycle of the near elimination and subsequent regeneration of the scroll wave is then repeated over and over again.

We find that, if

Furthermore, if we view the scroll wave in three dimensions, we find that its filament distorts in such a way that it remains attached to the obstacle at more than one point along its length in the transmural direction; the spiral sections of such a scroll wave appear pinned to the obstacle in some layers and detached from it in other layers.

For most parameter values, the scroll wave approaches the apex.

This anisotropy can lead to a twisting of scroll-wave filaments and break up of scroll waves even if the excitability is not low [37] [39].

In silico studies have a significant advantage over experimental ones when we consider rotating scroll waves or scroll-wave turbulence in three-dimensional cardiac tissue because we can visualize scroll-wave dynamics in three-dimensional computational domains in much more detail than is possible experimentally.

Subsection No inhomogeneities deals with the investigation of scroll-wave dynamics in the absence of localized inhomogeneities.

We turn now to a systematic study of scroll-wave dynamics in the 3D TNNP model with FR and inhomogeneities; we consider both conduction and ionic inhomogeneities.

Within the region that supports scroll-wave activity, the filament is anchored to the obstacle in some layers but not in others.
