The U wave in atrial fibrillation
Presentation / Conference Contribution
Langley, P., Bourke, J. P., & Murray, A. The U wave in atrial fibrillation. Presented at 2015 Computing in Cardiology Conference (CinC)

The U wave in ECGs of patients is difficult to observe because it is hidden under the atrial fibrillatory wave. Measurement and characteristics of the U wave in atrial fibrillation have not previously been described. Beat averaging was used to reveal... Read More about The U wave in atrial fibrillation.

The effect of beat interval on ventricular repolarisation in atrial fibrillation
Presentation / Conference Contribution
Al-Karadi, M. S., Wilkinson, A. J., & Langley, P. (2018, September). The effect of beat interval on ventricular repolarisation in atrial fibrillation. Presented at 2018 Computing in Cardiology Conference (CinC), Maastricht, The Netherlands

© 2018 Creative Commons Attribution. Atrial fibrillation (AF) is characterised by rapid beat interval changes. The aim of the study was to investigate the effect of such changes on ECG ventricular repolarisation characteristics. In 10 AF recordings b...

Abnormal heart sounds detected from short duration unsegmented phonocardiograms by wavelet entropy
Presentation / Conference Contribution
Langley, P., & Murray, A. Abnormal heart sounds detected from short duration unsegmented phonocardiograms by wavelet entropy

© 2016 CCAL. Segmentation of the characteristic heart sounds is thought to be an essential requirement for the automatic classification of phonocardiograms. The aim of this work was to test the feasibility of classification using short duration, unse...

Comparison of body surface and intracardiac ECG recordings in patients with atrial fibrillation during electrophysiological studies
Presentation / Conference Contribution
Bojarnejad, M., Blake, J., Bourke, J. P., Murray, A., & Langley, P. Comparison of body surface and intracardiac ECG recordings in patients with atrial fibrillation during electrophysiological studies. Presented at World Congress on Medical Physics and Biomedical Engineering May 26-31, 2012, Beijing, China

Atrial fibrillation (AF) dominant frequency (DF) is thought to reflect the degree of organisation of underlying atrial activity (AA). Our aim was to evaluate the relationship between the DFs from the body surface electrocardiogram (ECG) and intracard...
