The effect of beat interval on ventricular repolarisation in atrial fibrillation (2019)
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...

Validation of an algorithm to reveal the U wave in atrial fibrillation (2018)
Journal Article
Al-Karadi, M. S., Wilkinson, A. J., Caldwell, J., & Langley, P. (2018). Validation of an algorithm to reveal the U wave in atrial fibrillation. Scientific reports, 8(1), Article 11946. https://doi.org/10.1038/s41598-018-30493-8

Major cardiac organisations recommend U wave abnormalities should be reported during ECG interpretation. However, U waves cannot be measured in patients with atrial fibrillation (AF) due to the obscuring fibrillatory wave. The aim was to validate a U...

An ultrasonic transducer transient compensator design based on a simplified Variable Structure Control algorithm (2013)
Journal Article
Ma, S., Wilkinson, A. J., & Paulson, K. S. (2014). An ultrasonic transducer transient compensator design based on a simplified Variable Structure Control algorithm. Ultrasonics, 54(2), 502-515. https://doi.org/10.1016/j.ultras.2013.07.017

A non-linear control method, known as Variable Structure Control (VSC), is employed to reduce the duration of ultrasonic (US) transducer transients. A physically realizable system using a simplified form of the VSC algorithm is proposed for standard...
