The total character count for submission is 2,500 characters and does not include the Abstract Title. Spaces are included. Images will deduct up to 560 characters (based on image resolution) and image captions are also included in the character count.

No, all authors do not have to be members of HRS, but they DO need to have an HRS account. Please visit www.hrsonline.org to create an HRS account.

No, there is no maximum.

No, the submitting author will submit disclosures prior to submission and the presenting author will be required to submit disclosures prior to accepting the invitation to present. 

The system will default to have the submitting author listed as the presenting author. However, the presenting author can be changed to any of the co-authors by simply selecting the button for "Presenter" next to the desired co-author's name.

Before submitting, you can change the order of listed authors by dragging and dropping them into the desired order. You can also select which author will present. Author order can be changed up until the submission deadline. 

If an abstract is accepted, the submitting author will be given a chance to make changes to author order up until the abstract withdrawal deadline. After that point, no changes to author order will be accepted, however a change in presenting author can be requested by emailing abstracts@HRSonline.org. 

We will accept adapted/repurposed abstracts but not strictly encore abstracts. The submitted abstract should contain new material or data, new analysis or interpretations.

The submitting author will be notified of abstract acceptance on February 21, 2025. 

The submission fee is $175 for HRS members and $275 for non-members. The submitting author is responsible for this fee upon submission.

Please view our 2023 open access Abstract Catalog for examples of abstract submissions. 

The system will not allow you to submit an abstract that is missing required fields. If you attempt to move on to the next section or submit, you will receive an error message. Once you have completed all required fields and submit your abstract, the submitting author will receive a confirmation email as well as a payment receipt. 

In addition, the submitted abstract will appear under "Submissions" of the submitting author's account at hrs2025.abstractcentral.com.

Before the submission deadline, the submitting author can make changes to the abstract by returning it to draft status. Please be sure to resubmit the abstract prior to the submission deadline or the abstract will not be eligible for consideration at Heart Rhythm 2025.

After the submission deadline, no edits will be allowed to the abstract submission. Please carefully review your submission prior to the deadline to ensure accuracy. 

Where authors use generative artificial intelligence (AI) and AI-assisted technologies in the writing process, authors should only use these technologies to improve readability and language. Applying the technology should be done with human oversight and control, and authors should carefully review and edit the result, as AI can generate authoritative-sounding output that can be incorrect, incomplete or biased. AI and AI-assisted technologies should not be listed as an author or co-author, or be cited as an author. Authorship implies responsibilities and tasks that can only be attributed to and performed by humans.

HRS follows the guidelines of our publisher, Elsevier, in their AI policy for authors. We do not permit the use of Generative AI or AI-assisted tools to create or alter images. This may include enhancing, obscuring, moving, removing, or introducing a specific feature within an image or figure. Adjustments to brightness, contrast, or color balance are acceptable if and as long as they do not obscure or eliminate any information present in the original. 

The only exception is if the use of AI or AI-assisted tools is part of the research design or research methods (such as in AI-assisted imaging approaches to generate or interpret the underlying research data). IF this is done, such use must be described in a reproducible manner in the methods section. This should include and explanation of how the AI or AI-assisted tools were used in the image creation or alteration process, and the name of the model or tool, version and extension numbers, and manufacturer. Authors should adhere to the AI software's specific usage policies and ensure correct content attribution. Where applicable, authors could be asked to provide pre-AI-adjusted versions of images and/or the composite raw images used to create the final submitted versions. 

If submitting a full manuscript to one of our journals, authors should disclose in their manuscript the use of AI and AI-assisted technologies in the writing process by following the instructions below. A statement will appear in the published work. Please note that authors are ultimately responsible and accountable for the contents of the work.

Disclosure Instructions

Authors must disclose the use of generative AI and AI-assisted technologies in the writing process by adding a statement at the end of their manuscript in the core manuscript file, before the References list. The statement should be placed in a new section entitled 'Declaration of Generative AI and AI-assisted technologies in the writing process'.

Statement: During the preparation of this work the author(s) used [NAME TOOL/SERVICE] in order to [REASON]. After using this tool/service, the author(s) reviewed and edited the content as needed and take(s) full responsibility for the content of the publication.

This declaration does not apply to the use of basic tools for checking grammar, spelling, references, etc. If there is nothing to disclose, there is no need to add a statement.

The submitter is notified of the acceptance, but the presenting author is the one who is sent the invitation to present which will show which type of presentation they are assigned.

No, it is not required. We operate on the assumption that you have already completed all essential measures to safeguard your patient's identity and uphold their privacy.
