New technique offers improved diagnostic precision, possible personalized therapy for common arrhythmia

A multidisciplinary study led by scientists at the Centro Nacional de Investigaciones Cardiovasculares (CNIC) presents a new method for assessing the structural and electrophysiological changes, called atrial remodeling, produced in the heart of patients with atrial fibrillation, one of the most frequent forms of cardiac arrhythmia. The new diagnostic method is based on the simultaneous assessment of electrical and mechanical (contractile) activity in the heart atria during atrial fibrillation. The study is published in Nature Communications.
