Atrial Fibrillation from an Engineering Perspective is a book just released by Springer in their Series of Bioengineering, with Leif Sörnmo as editor and main author and Frida Sandberg as one the coauthors. The book provides an up-to-date overview of techniques developed for acquisition, modeling, and analysis of noninvasive, bioelectrical signals characterizing this common arrhythmia. Special emphasis is put on emerging technologies for monitoring of atrial fibrillation in connection with ischemic stroke, interventional ablation procedures, and pharmacological treatment – applications which all depend on the availability of algorithms for detecting and characterizing episodes of paroxysmal atrial fibrillation.
