Innovators Abstracts Session
The  Heart  Rhythm  Society  introduced  an  exciting  new  abstract  category  this  year  to  allow  innovative physicians and scientists to share new and novel approaches, techniques, and technologies.  Rather than looking for the completed results of scientific studies, these abstracts are based on their originality and scientific and clinical promise.

Innovators Poster Sessions will be presented on Thursday, May 5 and Friday, May 6 in the Esplanade Foyer (Moscone South building). Posters will be on display from 9:00 a.m. to 5:00 p.m. Presenters will be available at their poster from 9:30 -10:30 a.m. and 3:15 – 4:15 p.m.
