Computers in Cardiology Challenge 2004 Top Scores (Final)
Over twenty teams participated in this year's Challenge, on the topic of predicting if (or when) an episode of atrial fibrillation will self-terminate.
During September's Computers in Cardiology conference, we presented four awards to eligible participants in this year's challenge. In each event, an overall best award went to the top-scoring team, and a "best open source" award went to the top-scoring team among those who contributed the source code for their entries. The overall award in event 1 was presented to Dieter Hayn and his colleagues, and the overall award in event 2, as well as the "best open source" awards in both events, were won by Federico Cantini and his colleagues.

We wish to thank all those who participated in the challenge and in the lively and illuminating discussions during the scientific sessions of Computers in Cardiology. Brief descriptions of the methods used can be viewed by following the links in the tables below to abstracts submitted by the entrants for presentation at Computers in Cardiology 2004.

* The top-scoring entry in each of the two events came from the research group of Steven Swiryn of Northwestern University, who had contributed the data used in the challenge. Although these entries were thus ineligible for an award, Simona Petrutiu and her coauthors did not have access to any information beyond what was available to all of the participants, and we wish to recognize her extraordinary achievement in achieving a near-perfect score in event 1 and a perfect score in event 2.
Four additional teams of participants also described their approaches to the challenge:
AN Esgiar, PK Chakravorty

Medical Physics Dept, Freeman Hospital, Newcastle upon Tyne, UK
LT Mainardi, M Matteucci, R Sassi
Dipartimento di Bioingegneria, Politecnico di Milano, Milano, Italy
