Researchers at Columbia Engineering School have been developing a new method, Electromechanical Wave Imaging (EWI), that is the first non-invasive technique to map the electrical activation of the heart. Based on ultrasound imaging, EWI will enable doctors to treat arrhythmias more efficiently and more precisely. The study was published online in the May 9th Proceedings of the National Academy of Sciences. http://medicalxpress.com/news/2011-05-method-heart-arrhythmias.html Medical research Mon, 09 May 2011 15:57:32 EST news224175399
