Call for Science - Late Breaking Clinical Trials


Submit Your Late Breaking Clinical Trial!

The Heart Rhythm Society recognizes that exciting and rapidly evolving research was not concluded in time for the December 7, 2018 abstract submission deadline. To highlight timely and novel work at Heart Rhythm 2019, the Scientific Sessions Program Committee is now accepting late breaking abstracts to be peer reviewed and presented in session(s). 

The deadline to submit your LBCT Abstract Submission is Friday, March 8, 2019, 11:59 p.m. Submit your science today!


Each LBCT abstract submission will require a fee of $75 for HRS members and $150 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. Awards will be given to the highest scoring abstract in each category with a fellow-in-training as first author. If funds allow, additional awards will be awarded to the highest scoring (or second highest if an author has already been selected) abstract from each continent with a fellow-in-training as first author.

You Spoke. We Listened.

HRS received a large volume of recommendations from our attendees, members and volunteers to improve our Scientific Sessions offerings. The most repeated request was to provide more support for fellows and clinicians from the developing world. In light of this feedback, HRS explored ways to enable wider participation this year. The result is we are waiving registration fees for HRS members from the 28 countries identified by the World Bank as Low or Lower-Middle Income. Fellows-in-training can join HRS for free and early career EPs may receive considerable discounts for HRS membership.

Regulatory Factors

Increasing regulations from PhRMA & AdvaMed in the U.S., Eucomed in Europe, and other groups around the globe have resulted in a reduction of support for clinicians to attend scientific meetings. Additionally, the eligibility rules have become more complex leading many companies to reduce or eliminate this form of funding. Our abstract submission fee was introduced in an effort to support Heart Rhythm Scientific Session attendance by those who have traditionally relied on outside funding.


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.
