Accuracy of pulse interval timing in ambulatory blood pressure measurement (2016)
Journal Article
Kane, S. A., Blake, J. R., McArdle, F. J., Langley, P., & Sims, A. J. (2016). Accuracy of pulse interval timing in ambulatory blood pressure measurement. Scientific reports, 6(1), Article 37472. https://doi.org/10.1038/srep37472

Blood pressure (BP) monitors rely on pulse detection. Some blood pressure monitors use pulse timings to analyse pulse interval variability for arrhythmia screening, but this assumes that the pulse interval timings detected from BP cuffs are accurate...

The atrial T wave: The elusive electrocardiographic wave exposed by a case of shifting atrial pacemaker (2016)
Journal Article

The atrial T wave (Ta wave) is the body surface manifestation of atrial repolarisation and, unlike the P wave (atrial depolarisation), is little recognised. We report the case of a patient with shifting pacemaker which clearly demonstrates the effect...

Opportunistic detection of atrial fibrillation using blood pressure monitors: a systematic review (2016)
Journal Article

Background: Atrial Fibrillation (AF) affects around 2% of the population and early detection is beneficial, allowing patients to begin potentially life-saving anticoagulant therapies. Blood pressure (BP) monitors may offer an opportunity to screen fo... Read More about Opportunistic detection of atrial fibrillation using blood pressure monitors: a systematic review.

Abnormal heart sounds detected from short duration unsegmented phonocardiograms by wavelet entropy (2016)
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...

The U wave in atrial fibrillation (2016)
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.
