Biomedical Sciences Research Seminar Series

As part of the School of Science and Technology Biomedical Sciences Research Centre Seminar Series, Dr Frederique Vanheusden, NTU presents: Atrial fibrillation source detection for guiding catheter ablation.

Abstract

Atrial fibrillation (AF) is the most common cardiac arrhythmia in the world. Although not lethal by itself, AF significantly increases risk to suffer from disabling or lethal conditions such as stroke. AF patients whose cardiac rhythm cannot be converted pharmacologically are often treated with catheter ablation. Although several strategies have been suggested, identifying AF sources remains cumbersome, leading to low ablation success rates. Besides this, source identification is performed invasively, leading to increased risks for the patient. Strategies for non-invasive estimation of AF sources through electrocardiograms (ECGs) are currently being investigated. This presentation will discuss two invasive AF source detection strategies (dominant frequency and rotor analysis) and their limitations. It will then discuss potential caveats on extrapolating these strategies into non-invasive assessments.

This seminar is hosted by Dr Yvonne Reinwald
