Mapping Atrial Fibrillation in 2020: Key Updates, Emerging Techniques, Unresolved Issues-Body Surface Mapping

Video Transcription

Video Summary

In this presentation, Felipe Atienza discusses the use of body surface mapping in the study of atrial fibrillation (AFib). AFib is characterized by irregular electrical activity in the heart, and identifying the sources of this activity can help guide treatment. Traditional methods for mapping AFib have limitations, so Atienza and his team have turned to non-invasive body surface potential mapping. This technique involves using a large number of surface electrodes to record the electrical potentials on the body surface and then using computational models to calculate the electrical activity on the heart's surface. Atienza presents results showing the correlation between surface and intracardiac recordings, as well as the identification of atrial fibrillation sources using surface recording. He also discusses the use of body surface mapping in guiding ablation procedures and predicting treatment outcomes. Overall, body surface mapping shows promise as an accurate and personalized tool for studying AFib and guiding treatment decisions.
