Wavelet entropy as a measure of ventricular beat suppression from the electrocardiogram in atrial fibrillation (2015)
Journal Article
Langley, P. (2015). Wavelet entropy as a measure of ventricular beat suppression from the electrocardiogram in atrial fibrillation. Entropy, 17(9), 6397-6411. https://doi.org/10.3390/e17096397

A novel method of quantifying the effectiveness of the suppression of ventricular activity from electrocardiograms (ECGs) in atrial fibrillation is proposed. The temporal distribution of the energy of wavelet coefficients is quantified by wavelet ent...

Objective To assess the effect of catheter ablation on atrial fibrillation (AF) symptoms and quality of life (QoL). Methods Patients with AF scheduled for ablation were recruited. Pulmonary vein isolation (PVI) was performed and complex fractionated...

Principal component analysis of atrial fibrillation: Inclusion of posterior ECG leads does not improve correlation with left atrial activity (2015)
Journal Article
Raine, D., Langley, P., Shepherd, E., Lord, S., Murray, S., Murray, A., & Bourke, J. P. (2015). Principal component analysis of atrial fibrillation: Inclusion of posterior ECG leads does not improve correlation with left atrial activity. Medical engineering & physics, 37(2), 251-255. https://doi.org/10.1016/j.medengphy.2014.12.008

Background Lead V₁ is routinely analysed due to its large amplitude AF waveform. V₁ correlates strongly with right atrial activity but only moderately with left atrial activity. Posterior lead V₉ correlates strongest with left atrial activity. Aims (...

A new algorithm to diagnose atrial ectopic origin from multi lead ECG systems - insights from 3D virtual human atria and torso. PLoS Computational Biology, 11(1), Article e1004026. https://doi.org/10.1371/journal.pcbi.1004026

Rapid atrial arrhythmias such as atrial fibrillation (AF) predispose to ventricular arrhythmias, sudden cardiac death and stroke. Identifying the origin of atrial ectopic activity from the electrocardiogram (ECG) can help to diagnose the early onset...
