Diagnosing cardiac arrythmia has long been difficult, as the manifestation of its symptoms are unpredictable and monitoring devices are awkward and uncomfortable to wear.  That’s why idiom was so excited to be asked by iRhythm to name its revolutionary new device—a simple, inconspicuous, easy-to-wear patch that continuously monitors the heart 24/7 and provides data in a clear format.  The device’s name, Zio™, comes from the distinctive sound of the second and third syllables of its generic descriptor—physiological monitoring patch.
