Research

The diagnostic algorithms within Cardea 20/20 ECG™ are built on the recent research of the company founders and other notable colleagues, particularly those at Stanford University and the University of Washington. These efforts have recently culminated in the publication of the International Consensus for ECG Interpretation in Athletes—formerly the Seattle Criteria. (see British Journal of Sports Medicine).

The following research papers, co-authored by the company founders, provide the background foundations leading to the development of Cardea 20/20 ECG.
