Multielectrode high-density catheters enable comprehensive maps of electrogram amplitude and timing, addressing the limitations of conventional activation mapping.
High-resolution, live, directional mapping aims to overcome the limitations of conventional activation mapping, such as time-consuming annotation and the need to map large areas of the cardiac chamber.
Conventional arrhythmia mapping involves building activation maps from numerous catheter placements and sequential acquisitions during a stable rhythm. Multielectrode high-density (HD) catheters have enabled comprehensive and dense maps of electrogram (EGM) amplitude and timing. Despite automated algorithms, activation mapping still involves time annotation, numerous acquisitions, and reannotation—often beyond the ability of an electrophysiologist to verify during mapping. Additionally, conventional activation mapping may involve using all or most of the cardiac chamber to locate the source of arrhythmia.
Deno et al. (Sun,) conducted a other in Arrhythmia. Multielectrode high-density (HD) catheters vs. Conventional arrhythmia mapping was evaluated. Multielectrode high-density catheters enable comprehensive maps of electrogram amplitude and timing, addressing the limitations of conventional activation mapping.
