Call for Science - Late-Breaking Clinical Trials


Submit Your Clinical Trial!

The Heart Rhythm Society recognizes that exciting and rapidly evolving research was not concluded in time for the December 9, 2019 abstract submission deadline. To highlight timely and novel work at #HRS2020, the Scientific Sessions Program Committee developed a peer-reviewed session of late-breaking clinical trials (LBCT) that allows for later submission.

The Late-Breaking Clinical Trials Submission Site is now open. The submission deadline is Friday, March 6, 2020, 11:59 PM EST 


Each abstract submission will require a fee of $175 for HRS members and $250 for nonmembers. Become an HRS member today to submit for free. Nonrefundable submission fees will be used to fund travel grants for fellows-in-training.  The Heart Rhythm Society (HRS) encourages and supports the efforts of early career electrophysiologists and other heart rhythm professionals to participate in the Society’s activities.

To that end, the Heart Rhythm Travel Scholarships support participation in the Annual Scientific Sessions with a complimentary registration to Heart Rhythm and up to $1,500 in reimbursement of travel costs.

Apply for the Travel Scholarship

The scholarship application deadline is Tuesday, February 11, 2020.


Payments must be made by credit card during the submission process. Visa, MasterCard, and American Express are accepted.


Submitters are encouraged to use the Late-Breaking Clinical Trials Submission Guidelines as a tool for success. This resource includes everything you need to know about submitting a clinical trial for presentation at the Annual Scientific Sessions.
