Phase-Aligned Atrial Fibrillation Mapping

Sponsor: Larisa Tereshchenko, MD, PhD

Summary

Cardiac arrhythmia in the upper chamber of the heart (atrial fibrillation) can be cured by burning. Physicians burn very small pieces of abnormal tissue. It is important to know where to burn. The investigators propose a new way to find out where to burn. The investigators will use a new way to analyze electrical signals inside the heart and build a new electric map. The study may lead to the development of new technology. In the future, novel technology may increase the success rate and the number of cured atrial fibrillation patients. This study is a retrospective study of data collected during routine clinical care: atrial fibrillation ablations. The investigators will compare intracardiac electrograms and atrial activation maps in patients who had successful ablation outcomes (no recurrence within 1 year) and those who experienced a recurrence of arrhythmia within 1 year after the procedure.
