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.
