Background

Research in cardiac arrhythmias and cardiac electrophysiology is increasingly dependent on computational methods to relate experimental and clinical observations to the underlying mechanisms. Computational methods are essential to process experimental data (e.g., from optical mapping and body-surface potential mapping) and to model the biophysical processes underlying electrophysiology (e.g., inverse solutions of electrocardiography and cell and whole-heart modeling). Processing signals from experimental and clinical recordings can serve to elucidate electrophysiological properties across temporal, spatial and frequency domains. Computational modeling provides an understanding of fundamental aspects of cardiac electrophysiology from a theoretical standpoint. Additionally, patient-specific computational models are increasingly employed to interpret experimental and clinical observations to provide improved approximations of cardiac electrical behavior at an individual level. Advances in computational methodology are thus essential to obtain new insights in cardiac electrophysiology and arrhythmias.

This Research Topic addresses innovations in computational methodology and the synergy they bring with experimental and clinical data for cardiac electrophysiology. The primary aim of the Topic is to highlight state-of-the-art computational advancements that involve experimental or clinical signal analysis for optical and electrical mapping, biophysical modeling of electrophysiology, and inverse solutions. This includes advancements for (clinical) mapping systems (e.g., improved electrogram annotation), improved accuracy of inverse solutions and optical mapping, better understanding of electromechanical interactions, innovation of computational cell/heart models, or new experimental data that support such advancements. Moreover, computational and analytical approaches that aim to improve personalized diagnostics and therapy will also be sought after. Importantly, this Research Topic focuses on research where advancements in computational methods improve synergy with data, and may consequently bring new insights in electrophysiology and arrhythmias.

This research topic has the following computational methodology in scope:

• Body-surface potential mapping and electrocardiographic imaging

• Optical mapping of electrophysiology

• Electrogram processing for invasive and noninvasive recordings

• Cellular and whole-heart modeling of electrophysiology

• Studying the impact of mechanical deformation on electrophysiology

For all of these, relating the advancement in methodology to the synergy with experimental or clinical data in electrophysiology is highly recommended.

Frequently asked questions

  • Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

    Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

  • The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

    Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

  • As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

    A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

  • Each Research Topic must be approved by the specialty chief editor, and they fall under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

      In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

  • Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

    As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

    Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.
