The use of the ECG for atrial fibrillation (AF) in clinical daily practice is still limited to its diagnosis. Recent research shows however that ECG-derived parameters can also be used to assess the spatiotemporal properties of AF.


Specifically, frequency and the complexity of the f-waves in the ECG reflects the complexity of the fibrillatory conduction during AF and therefore can be used for quantification of the degree of electrophysiological alterations in the atria. This information might be useful for guiding AF therapy and might form the basis for classification of AF. 

YourRhythmics offers a high resolution ECG recorder and software to determine the frequency and complexity dynamics of atrial fibrillation non-invasively. Our ambition is to provide a decision-support tool to choose the most effective therapy for the individual AF patient.


The YRS100 is a CE approved 40-channel cardiac amplifier capable of measuring non-invasive ECG-signals. The device records these signals with a sampling rate of 2 kHz per channel and a 24 bits resolution to provide excellent signal quality. 


The YRS100 data acquisition software provides tools for easy configuration and setup, data visualisation  storage, and review and export of data. Signals and parameters can be checked in the display mode, stored to disk, and later reviewed in the offline mode or exported for further analysis. 


The YRS100 AF analysis software is an interactive environment for multimodal ECG data processing and analysis. The calculation of the complexity of Atrial Fibrillation is based on clinical validated studies.
